12 | /* |
13 | Here are brief descriptions of the filename formats supported by this class: | |
14 | ||
2bc60417 RR |
15 | wxPATH_UNIX: standard Unix format, used under Darwin as well, absolute file |
16 | names have the form: | |
04c943b1 VZ |
17 | /dir1/dir2/.../dirN/filename, "." and ".." stand for the |
18 | current and parent directory respectively, "~" is parsed as the | |
19 | user HOME and "~username" as the HOME of that user | |
20 | ||
2bc60417 | 21 | wxPATH_DOS: DOS/Windows format, absolute file names have the form: |
04c943b1 VZ |
22 | drive:\dir1\dir2\...\dirN\filename.ext where drive is a single |
23 | letter. "." and ".." as for Unix but no "~". | |
24 | ||
25 | There are also UNC names of the form \\share\fullpath | |
26 | ||
ae4d7004 | 27 | wxPATH_MAC: Mac OS 8/9 and Mac OS X under CodeWarrior 7 format, absolute file |
2bc60417 | 28 | names have the form |
04c943b1 VZ |
29 | volume:dir1:...:dirN:filename |
30 | and the relative file names are either | |
31 | :dir1:...:dirN:filename | |
32 | or just | |
33 | filename | |
34 | (although :filename works as well). | |
a385b5df | 35 | Since the volume is just part of the file path, it is not |
353f41cb | 36 | treated like a separate entity as it is done under DOS and |
90a68369 | 37 | VMS, it is just treated as another dir. |
04c943b1 VZ |
38 | |
39 | wxPATH_VMS: VMS native format, absolute file names have the form | |
40 | <device>:[dir1.dir2.dir3]file.txt | |
41 | or | |
42 | <device>:[000000.dir1.dir2.dir3]file.txt | |
43 | ||
44 | the <device> is the physical device (i.e. disk). 000000 is the | |
45 | root directory on the device which can be omitted. | |
46 | ||
47 | Note that VMS uses different separators unlike Unix: | |
48 | : always after the device. If the path does not contain : than | |
49 | the default (the device of the current directory) is assumed. | |
ba623ba2 | 50 | [ start of directory specification |
04c943b1 VZ |
51 | . separator between directory and subdirectory |
52 | ] between directory and file | |
