|
Here are brief descriptions of the filename formats supported by this class:
|
|
|
|
wxPATH_UNIX: standard Unix format, used under Darwin as well, absolute file
|
|
names have the form:
|
|
/dir1/dir2/.../dirN/filename, "." and ".." stand for the
|
|
current and parent directory respectively, "~" is parsed as the
|
|
user HOME and "~username" as the HOME of that user
|
|
|
|
wxPATH_DOS: DOS/Windows format, absolute file names have the form:
|
|
drive:\dir1\dir2\...\dirN\filename.ext where drive is a single
|
|
letter. "." and ".." as for Unix but no "~".
|
|
|
|
There are also UNC names of the form \\share\fullpath
|
|
|
|
wxPATH_MAC: Mac OS 8/9 and Mac OS X under CodeWarrior 7 format, absolute file
|
|
names have the form
|
|
volume:dir1:...:dirN:filename
|
|
and the relative file names are either
|
|
:dir1:...:dirN:filename
|
|
or just
|
|
filename
|
|
(although :filename works as well).
|
|
Since the volume is just part of the file path, it is not
|
|
treated like a separate entity as it is done under DOS and
|
|
VMS, it is just treated as another dir.
|
|
|
|
wxPATH_VMS: VMS native format, absolute file names have the form
|
|
<device>:[dir1.dir2.dir3]file.txt
|
|
or
|
|
<device>:[000000.dir1.dir2.dir3]file.txt
|
|
|
|
the <device> is the physical device (i.e. disk). 000000 is the
|
|
root directory on the device which can be omitted.
|
|
|
|
Note that VMS uses different separators unlike Unix:
|
|
: always after the device. If the path does not contain : than
|
|
the default (the device of the current directory) is assumed.
|
|
[ start of directory specyfication
|
|
. separator between directory and subdirectory
|
|
] between directory and file
