#error "Do not use this file. The unix compilers do not support standard C++. Use nsFileStream"

// First checked in on 98/11/20 by John R. McMullen in the wrong directory.
|
|
// Checked in again 98/12/04.
|

// Polished version 98/12/08.

|
|
//========================================================================================
|
|
//
|
|
// Classes defined:
|
|
//
|
|
// single-byte char:
|
|
//
|
|
// nsInputFileStream, nsOutputFileStream, nsIOFileStream
|
|
//
|
|
// wide char:
|
|
//
|
|
// nsWideInputFileStream, nsWideOutputFileStream, nsWideIOFileStream
|
|
//
|
|
// This suite provide the following services:
|
|
//
|
|
// 1. Encapsulates all platform-specific file details, so that file i/o
|
|
// can be done correctly without any platform #ifdefs
|
|
//
|
|
// 2. Uses NSPR file services (NOT ansi file I/O), in order to get best
|
|
// native performance. This performance difference is especially large on
|
|
// macintosh.
|
|
//
|
|
// 3. Allows all the power of the ansi stream syntax: these streams
|
|
// ARE derived classes of ostream, istream, and iostream. ALL METHODS OF
|
|
// istream, ostream, AND iostream ARE AVAILABLE!
|
|
//
|
|
// Basic example:
|
|
//
|
|
// nsFilePath myPath("/Development/iotest.txt");
|
|
//
|
|
// nsOutputFileStream testStream(myPath);
|
|
// testStream << "Hello World" << endl;
|
|
//
|
|
// 4. Requires streams to be constructed using typesafe nsFilePath specifier
|
|
// (not the notorious and bug prone const char*), namely nsFilePath. See
|
|
// nsFileSpec.h for more details.
|
|
//
|
|
// 5. Fixes a bug that have been there for a long time, and
|
|
// is inevitable if you use NSPR alone:
|
|
//
|
|
// The problem on platforms (Macintosh) in which a path does not fully
|
|
// specify a file, because two volumes can have the same name.
|
|
//
|
|
// Not yet provided:
|
|
//
|
|
// Endian-awareness for reading and writing crossplatform binary files. At this
|
|
// time there seems to be no demand for this.
