Notes:
|
|
What do those arrows in the documentation for each routine mean?
|
|
|
|
--> The parameter is an input
|
|
|
|
<-- The parameter is an output. The pointer to the variable
|
|
where the output will be returned (must not be NULL).
|
|
|
|
<** The parameter is an optional output. If it is not a
|
|
NULL pointer, it points to the variable where the output
|
|
will be returned. If it is a NULL pointer, the output will
|
|
not be returned and will possibly let the routine and the
|
|
File Manager do less work. If you don't need an optional output,
|
|
don't ask for it.
|
|
**> The parameter is an optional input. If it is not a

1, FSExchangeObjectsCompat will work on volumes which do not support

2. FSExchangeObjectsCompat returns new FSRefs to the source and

|
destination files. Note that if this function fails at any step along

|
the way, newSourceRef and newDestRef still give you access to the final
|

the file ID reference and returns the result code fidExists or afpIDExists.

/*
|
|
Why is there no FSDeleteFileIDRef routine? There are two reasons:
|
|
|
|
1. Since Mac OS 8.1, PBDeleteFileIDRef hasn't deleted file ID references.
|
|
On HFS volumes, deleting a file ID reference breaks aliases (which
|
|
use file ID references to track files as they are moved around on a
|
|
volume) and file ID references are automatically deleted when the file
|
|
they refer to is deleted. On HFS Plus volumes, file ID references are
|
|
always created when a file is created, deleted when the file is deleted,
|
|
and cannot be deleted at any other time.
|
|
|
|
2. PBDeleteFileIDRef causes a memory access fault under Mac OS X 10.0
|
|
through 10.1.x. While this will be fixed in a future release, the
|
|
implementation, like the Mac OS 8/9 implementation, does not delete
|
|
file ID references.
