Parameter Discussion
The driveName, directoryName, and fileName parameters can each be NULL. If not NULL,
they must be buffers of the following size or greater.
drive name MAX_DRIVENAME_LEN
directory name MAX_DIRNAME_LEN
file name MAX_FILENAME_LEN
On operating systems without drive names (such as UNIX), driveName will always be filled in
with the empty string.
Example
char pathName[MAX_PATHNAME_LEN];
char driveName[MAX_DRIVENAME_LEN];
char dirName[MAX_DIRNAME_LEN];
char fileName[MAX_FILENAME_LEN];
SplitPath (pathName, driveName, dirName, fileName);
/* If pathName contains
c:\cvi\samples\apps\update.c
then
driveName contains
“
c:
”
dirName contains
“
\cvi\samples\apps\
”
fileName contains
“
update.c
”
If pathName is
\\computer\share\dirname\foo.c
then
drive name is ""
directory name is " \\computer\share\dirname\"
file name is "foo.c"
