The rationale for attempting to do the lookup by name prior to doing it by uid is to accommodate the possibility of multiple login names (each with its own record in the password database, so each with a potentially different home directory) being mapped to the same uid (as is explicitly allowed for by POSIX; see getlogin(3posix)).

(We have similar experience at Ruby 1.9, for example "RARRAY(ary)->ptr" to "RARRAY_PTR(ary)". * internal.h: add some macros. * RBASIC_CLEAR_CLASS(obj) clear RBasic::klass to make it internal object. * RBASIC_SET_CLASS(obj, cls) set RBasic::klass. * RBASIC_SET_CLASS_RAW(obj, cls) same as RBASIC_SET_CLASS without write barrier (planned). * RCLASS_SET_SUPER(a, b) set super class of a. * array.c, class.c, compile.c, encoding.c, enum.c, error.c, eval.c, file.c, gc.c, hash.c, io.c, iseq.c, marshal.c, object.c, parse.y, proc.c, process.c, random.c, ruby.c, sprintf.c, string.c, thread.c, transcode.c, vm.c, vm_eval.c, win32/file.c: Use above macros and functions to access RBasic::klass. * ext/coverage/coverage.c, ext/readline/readline.c, ext/socket/ancdata.c, ext/socket/init.c, * ext/zlib/zlib.c: ditto. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@40691 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

ruby/ruby.h: remove unnecessary exports from C-API Needlessly exporting can reduce performance locally and increase binary size. Increasing the footprint of our C-API larger is also detrimental to our development as it encourages tighter coupling with our internals; making it harder for us to preserve compatibility. If some parts of the core codebase needs access to globals, internal.h should be used instead of anything in include/ruby/*.

* include/ruby/ruby.h: constify RBasic::klass and add RBASIC_CLASS(obj) macro which returns a class of `obj'. This change is a part of RGENGC branch [ruby-trunk - Feature #8339]. * object.c: add new function rb_obj_reveal(). This function reveal interal (hidden) object by rb_obj_hide(). Note that do not change class before and after hiding. Only permitted example is: klass = RBASIC_CLASS(obj); rb_obj_hide(obj); .... rb_obj_reveal(obj, klass); TODO: API design. rb_obj_reveal() should be replaced with others. TODO: modify constified variables using cast may be harmful for compiler's analysis and optimizaton. Any idea to prohibt inserting RBasic::klass directly? If rename RBasic::klass and force to use RBASIC_CLASS(obj), then all codes such as `RBASIC(obj)->klass' will be compilation error. Is it acceptable?

Fix compatibility of cached expanded load path * file.c (rb_get_path_check_to_string): extract from rb_get_path_check(). We change the spec not to call to_path of String object. * file.c (rb_get_path_check_convert): extract from rb_get_path_check(). * file.c (rb_get_path_check): follow the above change. * file.c (rb_file_expand_path_fast): remove check_expand_path_args(). Instead we call it in load.c. * file.c (rb_find_file_ext_safe): use rb_get_expanded_load_path() to reduce expand cost. * file.c (rb_find_file_safe): ditto. * internal.h (rb_get_expanded_load_path): add a declaration. * internal.h (rb_get_path_check_to_string, rb_get_path_check_convert): add declarations. * load.c (rb_construct_expanded_load_path): fix for compatibility. Same checks in rb_get_path_check() are added. We don't replace $LOAD_PATH and ensure that String object of $LOAD_PATH are frozen. We don't freeze non String object and expand it every times. We add arguments for expanding load path partially and checking if load path have relative paths or non String objects. * load.c (load_path_getcwd): get current working directory for checking if it's changed when getting load path. * load.c (rb_get_expanded_load_path): fix for rebuilding cache properly. We check if current working directory is changed and rebuild expanded load path cache. We expand paths which start with ~ (User HOME) and non String objects every times for compatibility.

* include/ruby/ruby.h: constify RBasic::klass and add RBASIC_CLASS(obj) macro which returns a class of `obj'. This change is a part of RGENGC branch [ruby-trunk - Feature #8339]. * object.c: add new function rb_obj_reveal(). This function reveal interal (hidden) object by rb_obj_hide(). Note that do not change class before and after hiding. Only permitted example is: klass = RBASIC_CLASS(obj); rb_obj_hide(obj); .... rb_obj_reveal(obj, klass); TODO: API design. rb_obj_reveal() should be replaced with others. TODO: modify constified variables using cast may be harmful for compiler's analysis and optimizaton. Any idea to prohibt inserting RBasic::klass directly? If rename RBasic::klass and force to use RBASIC_CLASS(obj), then all codes such as `RBASIC(obj)->klass' will be compilation error. Is it acceptable? (We have similar experience at Ruby 1.9, for example "RARRAY(ary)->ptr" to "RARRAY_PTR(ary)". * internal.h: add some macros. * RBASIC_CLEAR_CLASS(obj) clear RBasic::klass to make it internal object. * RBASIC_SET_CLASS(obj, cls) set RBasic::klass. * RBASIC_SET_CLASS_RAW(obj, cls) same as RBASIC_SET_CLASS without write barrier (planned). * RCLASS_SET_SUPER(a, b) set super class of a. * array.c, class.c, compile.c, encoding.c, enum.c, error.c, eval.c, file.c, gc.c, hash.c, io.c, iseq.c, marshal.c, object.c, parse.y, proc.c, process.c, random.c, ruby.c, sprintf.c, string.c, thread.c, transcode.c, vm.c, vm_eval.c, win32/file.c: Use above macros and functions to access RBasic::klass. * ext/coverage/coverage.c, ext/readline/readline.c, ext/socket/ancdata.c, ext/socket/init.c, * ext/zlib/zlib.c: ditto. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@40691 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

* A \File object is a representation of a file in the underlying platform.
*
* \Class \File extends module FileTest, supporting such singleton methods
* as <tt>File.exist?</tt>.
*
* == About the Examples
*
* Many examples here use these variables:
*
* :include: doc/examples/files.rdoc
*
* == Access Modes
*
2023-08-12 19:44:38 +03:00
* Methods File.new and File.open each create a \File object for a given file path.
*
* === \String Access Modes
*
2023-08-12 19:44:38 +03:00
* Methods File.new and File.open each may take string argument +mode+, which:
*
* - Begins with a 1- or 2-character
* {read/write mode}[rdoc-ref:File@Read-2FWrite+Mode].
* - May also contain a 1-character {data mode}[rdoc-ref:File@Data+Mode].
* - May also contain a 1-character
* {file-create mode}[rdoc-ref:File@File-Create+Mode].
*
* ==== Read/Write Mode
*
* The read/write +mode+ determines:
*
* - Whether the file is to be initially truncated.
*
* - Whether reading is allowed, and if so:
*
* - The initial read position in the file.
* - Where in the file reading can occur.
*
* - Whether writing is allowed, and if so:
*
* - The initial write position in the file.
* - Where in the file writing can occur.
*
* These tables summarize:
*
* Read/Write Modes for Existing File
*
* |------|-----------|----------|----------|----------|-----------|
* | R/W | Initial | | Initial | | Initial |
* | Mode | Truncate? | Read | Read Pos | Write | Write Pos |
* |------|-----------|----------|----------|----------|-----------|
* | 'r' | No | Anywhere | 0 | Error | - |
* | 'w' | Yes | Error | - | Anywhere | 0 |
* | 'a' | No | Error | - | End only | End |
* | 'r+' | No | Anywhere | 0 | Anywhere | 0 |
* | 'w+' | Yes | Anywhere | 0 | Anywhere | 0 |
* | 'a+' | No | Anywhere | End | End only | End |
* |------|-----------|----------|----------|----------|-----------|
*
* Read/Write Modes for \File To Be Created
*
* |------|----------|----------|----------|-----------|
* | R/W | | Initial | | Initial |
* | Mode | Read | Read Pos | Write | Write Pos |
* |------|----------|----------|----------|-----------|
* | 'w' | Error | - | Anywhere | 0 |
* | 'a' | Error | - | End only | 0 |
* | 'w+' | Anywhere | 0 | Anywhere | 0 |
* | 'a+' | Anywhere | 0 | End only | End |
* |------|----------|----------|----------|-----------|
*
* Note that modes <tt>'r'</tt> and <tt>'r+'</tt> are not allowed
* for a non-existent file (exception raised).
*
* In the tables:
*
* - +Anywhere+ means that methods IO#rewind, IO#pos=, and IO#seek
* may be used to change the file's position,
* so that allowed reading or writing may occur anywhere in the file.
* - <tt>End only</tt> means that writing can occur only at end-of-file,
* and that methods IO#rewind, IO#pos=, and IO#seek do not affect writing.
* - +Error+ means that an exception is raised if disallowed reading or writing
* is attempted.

* ==== \Data Mode
*
* To specify whether data is to be treated as text or as binary data,
* either of the following may be suffixed to any of the string read/write modes
* above:
*
* - <tt>'t'</tt>: Text data; sets the default external encoding
* to <tt>Encoding::UTF_8</tt>;
* on Windows, enables conversion between EOL and CRLF
* and enables interpreting <tt>0x1A</tt> as an end-of-file marker.
* - <tt>'b'</tt>: Binary data; sets the default external encoding
* to <tt>Encoding::ASCII_8BIT</tt>;
* on Windows, suppresses conversion between EOL and CRLF
* and disables interpreting <tt>0x1A</tt> as an end-of-file marker.
*
* If neither is given, the stream defaults to text data.
*
* Examples:
*
* File.new('t.txt', 'rt')
* File.new('t.dat', 'rb')
*
* When the data mode is specified, the read/write mode may not be omitted,
* and the data mode must precede the file-create mode, if given:
*
* File.new('t.dat', 'b') # Raises an exception.
* File.new('t.dat', 'rxb') # Raises an exception.
*
* ==== \File-Create Mode
*
* The following may be suffixed to any writable string mode above:
*
* - <tt>'x'</tt>: Creates the file if it does not exist;
* raises an exception if the file exists.
*
* Example:
*
* File.new('t.tmp', 'wx')
*
* When the file-create mode is specified, the read/write mode may not be omitted,
* and the file-create mode must follow the data mode:
*
* File.new('t.dat', 'x') # Raises an exception.
* File.new('t.dat', 'rxb') # Raises an exception.
*
* === \Integer Access Modes
*
* When mode is an integer it must be one or more of the following constants,
* which may be combined by the bitwise OR operator <tt>|</tt>:
*
* - +File::RDONLY+: Open for reading only.
* - +File::WRONLY+: Open for writing only.
* - +File::RDWR+: Open for reading and writing.
* - +File::APPEND+: Open for appending only.
*
* Examples:
*
* File.new('t.txt', File::RDONLY)
* File.new('t.tmp', File::RDWR | File::CREAT | File::EXCL)
*
* Note: Method IO#set_encoding does not allow the mode to be specified as an integer.
*
* === File-Create Mode Specified as an \Integer
*
* These constants may also be ORed into the integer mode:
*
* - +File::CREAT+: Create file if it does not exist.
* - +File::EXCL+: Raise an exception if +File::CREAT+ is given and the file exists.
*
2022-10-19 18:34:51 +03:00
* === \Data Mode Specified as an \Integer
*
2022-12-10 05:56:02 +03:00
* \Data mode cannot be specified as an integer.
* When the stream access mode is given as an integer,
* the data mode is always text, never binary.
*
* Note that although there is a constant +File::BINARY+,
* setting its value in an integer stream mode has no effect;
* this is because, as documented in File::Constants,
* the +File::BINARY+ value disables line code conversion,
* but does not change the external encoding.
*
* === Encodings
*
* Any of the string modes above may specify encodings -
* either external encoding only or both external and internal encodings -
* by appending one or both encoding names, separated by colons:
*
* f = File.new('t.dat', 'rb')
* f.external_encoding # => #<Encoding:ASCII-8BIT>
* f.internal_encoding # => nil
* f = File.new('t.dat', 'rb:UTF-16')
* f.external_encoding # => #<Encoding:UTF-16 (dummy)>
* f.internal_encoding # => nil
* f = File.new('t.dat', 'rb:UTF-16:UTF-16')
* f.external_encoding # => #<Encoding:UTF-16 (dummy)>
* f.internal_encoding # => #<Encoding:UTF-16>
* f.close
*
* The numerous encoding names are available in array Encoding.name_list:
*
* Encoding.name_list.take(3) # => ["ASCII-8BIT", "UTF-8", "US-ASCII"]
*
* When the external encoding is set, strings read are tagged by that encoding
* when reading, and strings written are converted to that encoding when
* writing.
*
* When both external and internal encodings are set,
* strings read are converted from external to internal encoding,
* and strings written are converted from internal to external encoding.
* For further details about transcoding input and output,
2022-11-09 19:15:39 +03:00
* see {Encodings}[rdoc-ref:encodings.rdoc@Encodings].
*
* If the external encoding is <tt>'BOM|UTF-8'</tt>, <tt>'BOM|UTF-16LE'</tt>
* or <tt>'BOM|UTF16-BE'</tt>,
* Ruby checks for a Unicode BOM in the input document
* to help determine the encoding.
* For UTF-16 encodings the file open mode must be binary.
* If the BOM is found,
* it is stripped and the external encoding from the BOM is used.
*
* Note that the BOM-style encoding option is case insensitive,
* so <tt>'bom|utf-8'</tt> is also valid.
*
* == \File Permissions
*
* A \File object has _permissions_, an octal integer representing
* the permissions of an actual file in the underlying platform.
*
* Note that file permissions are quite different from the _mode_
* of a file stream (\File object).
*
* In a \File object, the permissions are available thus,
* where method +mode+, despite its name, returns permissions:
*
* f = File.new('t.txt')
* f.lstat.mode.to_s(8) # => "100644"
*
* On a Unix-based operating system,
* the three low-order octal digits represent the permissions
* for owner (6), group (4), and world (4).
* The triplet of bits in each octal digit represent, respectively,
* read, write, and execute permissions.
*
* Permissions <tt>0644</tt> thus represent read-write access for owner
* and read-only access for group and world.
* See man pages {open(2)}[https://www.unix.com/man-page/bsd/2/open]
* and {chmod(2)}[https://www.unix.com/man-page/bsd/2/chmod].
*
* For a directory, the meaning of the execute bit changes:
* when set, the directory can be searched.
*
* Higher-order bits in permissions may indicate the type of file
* (plain, directory, pipe, socket, etc.) and various other special features.
*
* On non-Posix operating systems, permissions may include only read-only or read-write,
* in which case, the remaining permission will resemble typical values.
* On Windows, for instance, the default permissions are <code>0644</code>;
* The only change that can be made is to make the file
* read-only, which is reported as <code>0444</code>.
*
* For a method that actually creates a file in the underlying platform
* (as opposed to merely creating a \File object),
* permissions may be specified:
*
* File.new('t.tmp', File::CREAT, 0644)
* File.new('t.tmp', File::CREAT, 0444)
*
* Permissions may also be changed:
*
* f = File.new('t.tmp', File::CREAT, 0444)
* f.chmod(0644)
* f.chmod(0444)
*
2022-10-19 18:34:51 +03:00
* == \File \Constants
*
2023-08-12 19:44:38 +03:00
* Various constants for use in \File and IO methods
* may be found in module File::Constants;
* an array of their names is returned by <tt>File::Constants.constants</tt>.

/*
* Document-module: File::Constants
*
2023-07-23 17:24:19 +03:00
* \Module +File::Constants+ defines file-related constants.
*
2023-07-23 17:24:19 +03:00
* There are two families of constants here:
*
* - Those having to do with {file access}[rdoc-ref:File::Constants@File+Access].
2023-08-31 17:27:10 +03:00
* - Those having to do with {filename globbing}[rdoc-ref:File::Constants@Filename+Globbing+Constants+-28File-3A-3AFNM_-2A-29].
2023-07-23 17:24:19 +03:00
*
* \File constants defined for the local process may be retrieved
* with method File::Constants.constants:
*
* File::Constants.constants.take(5)
* # => [:RDONLY, :WRONLY, :RDWR, :APPEND, :CREAT]
*
* == \File Access
*
* \File-access constants may be used with optional argument +mode+ in calls
* to the following methods:
*
* - File.new.
* - File.open.
* - IO.for_fd.
* - IO.new.
* - IO.open.
* - IO.popen.
* - IO.reopen.
* - IO.sysopen.
* - StringIO.new.
* - StringIO.open.
* - StringIO#reopen.
*
* === Read/Write Access
*
* Read-write access for a stream
* may be specified by a file-access constant.
*
* The constant may be specified as part of a bitwise OR of other such constants.
*
* Any combination of the constants in this section may be specified.
*
* ==== File::RDONLY
*
* Flag File::RDONLY specifies the the stream should be opened for reading only:
*
* filepath = '/tmp/t.tmp'
* f = File.new(filepath, File::RDONLY)
* f.write('Foo') # Raises IOError (not opened for writing).
*
* ==== File::WRONLY
*
* Flag File::WRONLY specifies that the stream should be opened for writing only:
*
* f = File.new(filepath, File::WRONLY)
* f.read # Raises IOError (not opened for reading).
*
* ==== File::RDWR
*
* Flag File::RDWR specifies that the stream should be opened
* for both reading and writing:
*
* f = File.new(filepath, File::RDWR)
* f.write('Foo') # => 3
* f.rewind # => 0
* f.read # => "Foo"
*
* === \File Positioning
*
* ==== File::APPEND
*
* Flag File::APPEND specifies that the stream should be opened
* in append mode.
*
* Before each write operation, the position is set to end-of-stream.
* The modification of the position and the following write operation
* are performed as a single atomic step.
*
* ==== File::TRUNC
*
* Flag File::TRUNC specifies that the stream should be truncated
* at its beginning.
* If the file exists and is successfully opened for writing,
* it is to be truncated to position zero;
* its ctime and mtime are updated.
*
* There is no effect on a FIFO special file or a terminal device.
* The effect on other file types is implementation-defined.
* The result of using File::TRUNC with File::RDONLY is undefined.
*
* === Creating and Preserving
*
* ==== File::CREAT
*
* Flag File::CREAT specifies that the stream should be created
* if it does not already exist.
*
* If the file exists:
*
* - Raise an exception if File::EXCL is also specified.
* - Otherwise, do nothing.
*
* If the file does not exist, then it is created.
* Upon successful completion, the atime, ctime, and mtime of the file are updated,
* and the ctime and mtime of the parent directory are updated.
*
* ==== File::EXCL
*
* Flag File::EXCL specifies that the stream should not already exist;
* If flags File::CREAT and File::EXCL are both specified
* and the stream already exists, an exception is raised.
*
* The check for the existence and creation of the file is performed as an
* atomic operation.
*
* If both File::EXCL and File::CREAT are specified and the path names a symbolic link,
* an exception is raised regardless of the contents of the symbolic link.
*
* If File::EXCL is specified and File::CREAT is not specified,
* the result is undefined.
*
* === POSIX \File \Constants
*
* Some file-access constants are defined only on POSIX-compliant systems;
* those are:
*
* - File::SYNC.
* - File::DSYNC.
* - File::RSYNC.
* - File::DIRECT.
* - File::NOATIME.
* - File::NOCTTY.
* - File::NOFOLLOW.
* - File::TMPFILE.
*
* ==== File::SYNC, File::RSYNC, and File::DSYNC
*
* Flag File::SYNC, File::RSYNC, or File::DSYNC
* specifies synchronization of I/O operations with the underlying file system.
*
* These flags are valid only for POSIX-compliant systems.
*
* - File::SYNC specifies that all write operations (both data and metadata)
* are immediately to be flushed to the underlying storage device.
* This means that the data is written to the storage device,
* and the file's metadata (e.g., file size, timestamps, permissions)
* are also synchronized.
* This guarantees that data is safely stored on the storage medium
* before returning control to the calling program.
* This flag can have a significant impact on performance
* since it requires synchronous writes, which can be slower
* compared to asynchronous writes.
*
* - File::RSYNC specifies that any read operations on the file will not return
* until all outstanding write operations
* (those that have been issued but not completed) are also synchronized.
* This is useful when you want to read the most up-to-date data,
* which may still be in the process of being written.
*
* - File::DSYNC specifies that all _data_ write operations
* are immediately to be flushed to the underlying storage device;
* this differs from File::SYNC, which requires that _metadata_
* also be synchronized.
*
* Note that the behavior of these flags may vary slightly
* depending on the operating system and filesystem being used.
* Additionally, using these flags can have an impact on performance
* due to the synchronous nature of the I/O operations,
* so they should be used judiciously,
* especially in performance-critical applications.
*
* ==== File::NOCTTY
*
* Flag File::NOCTTY specifies that if the stream is a terminal device,
* that device does not become the controlling terminal for the process.
*
* Defined only for POSIX-compliant systems.
*
* ==== File::DIRECT
*
* Flag File::DIRECT requests that cache effects of the I/O to and from the stream
* be minimized.
*
* Defined only for POSIX-compliant systems.
*
* ==== File::NOATIME
*
* Flag File::NOATIME specifies that act of opening the stream
* should not modify its access time (atime).
*
* Defined only for POSIX-compliant systems.
*
* ==== File::NOFOLLOW
*
* Flag File::NOFOLLOW specifies that if path is a symbolic link,
* it should not be followed.
*
* Defined only for POSIX-compliant systems.
*
* ==== File::TMPFILE
*
* Flag File::TMPFILE specifies that the opened stream
* should be a new temporary file.
*
* Defined only for POSIX-compliant systems.
*
* === Other File-Access \Constants
*
* ==== File::NONBLOCK
*
* When possible, the file is opened in nonblocking mode.
* Neither the open operation nor any subsequent I/O operations on
* the file will cause the calling process to wait.
*
* ==== File::BINARY
*
* Flag File::BINARY specifies that the stream is to be accessed in binary mode.
*
* ==== File::SHARE_DELETE (Windows Only)
*
* Flag File::SHARE_DELETE enables other processes to open the stream
* with delete access.
*
* If the stream is opened for (local) delete access without File::SHARE_DELETE,
* and another process attempts to open it with delete access,
* the attempt fails and the stream is not opened for that process.
*
* == Locking
*
* Four file constants relate to stream locking;
* see File#flock:
*
* ==== File::LOCK_EX
*
* Flag File::LOCK_EX specifies an exclusive lock;
* only one process a a time may lock the stream.
*
* ==== File::LOCK_NB
*
* Flag File::LOCK_NB specifies non-blocking locking for the stream;
* may be combined with File::LOCK_EX or File::LOCK_SH.
*
* ==== File::LOCK_SH
*
* Flag File::LOCK_SH specifies that multiple processes may lock
* the stream at the same time.
*
* ==== File::LOCK_UN
*
* Flag File::LOCK_UN specifies that the stream is not to be locked.
*
* == Filename Globbing \Constants (File::FNM_*)
*
* Filename-globbing constants may be used with optional argument +flags+
* in calls to the following methods:
*
* - Dir.glob.
* - File.fnmatch.
* - Pathname#fnmatch.
* - Pathname.glob.
* - Pathname#glob.
*
* The constants are:
*
* ==== File::FNM_CASEFOLD
*
* Flag File::FNM_CASEFOLD makes patterns case insensitive
* for File.fnmatch (but not Dir.glob).
*
* ==== File::FNM_DOTMATCH
*
* Flag File::FNM_DOTMATCH makes the <tt>'*'</tt> pattern
* match a filename starting with <tt>'.'</tt>.
*
* ==== File::FNM_EXTGLOB
*
* Flag File::FNM_EXTGLOB enables pattern <tt>'{_a_,_b_}'</tt>,
* which matches pattern '_a_' and pattern '_b_';
* behaves like
* a {regexp union}[rdoc-ref:Regexp.union]
2023-07-23 17:24:19 +03:00
* (e.g., <tt>'(?:_a_|_b_)'</tt>):
*
* pattern = '{LEGAL,BSDL}'
* Dir.glob(pattern) # => ["LEGAL", "BSDL"]
* Pathname.glob(pattern) # => [#<Pathname:LEGAL>, #<Pathname:BSDL>]
* pathname.glob(pattern) # => [#<Pathname:LEGAL>, #<Pathname:BSDL>]
*
* ==== File::FNM_NOESCAPE
*
* Flag File::FNM_NOESCAPE disables <tt>'\'</tt> escaping.
*
* ==== File::FNM_PATHNAME
*
* Flag File::FNM_PATHNAME specifies that patterns <tt>'*'</tt> and <tt>'?'</tt>
* do not match the directory separator
* (the value of constant File::SEPARATOR).
*
* ==== File::FNM_SHORTNAME (Windows Only)
*
* Flag File::FNM_SHORTNAME Allows patterns to match short names if they exist.
*
* ==== File::FNM_SYSCASE
*
* Flag File::FNM_SYSCASE specifies that case sensitivity
* is the same as in the underlying operating system;
* effective for File.fnmatch, but not Dir.glob.
*
* == Other \Constants
*
* ==== File::NULL
*
* Flag File::NULL contains the string value of the null device:
*
* - On a Unix-like OS, <tt>'/dev/null'</tt>.
* - On Windows, <tt>'NUL'</tt>.
*
