Returns an OS-independant basename() of a given filename.
BEGIN_C_DECLS OPAL_DECLSPEC char* opal_basename | ( | const char * | filename | ) |
Return the basename of a filename.
filename | The filename to examine |
The contents of the filename parameter are unchanged. This function returns a new string containing the basename of the filename (which must be eventually freed by the caller), or NULL if there is an error. Trailing "/" characters in the filename do not count, unless it is in the only part of the filename (e.g., "/" or "C:\").
This function will do the Right Things on POSIX and Windows-based operating systems. For example:
foo.txt returns "foo.txt"
/foo/bar/baz returns "baz"
/yow.c returns "yow.c"
/ returns "/"
C: returns "baz"
D:foo.txt returns "foo.txt"
E:.c returns "yow.c"
F: returns "F:"
G:\ returns "G:"
The caller is responsible for freeing the returned string.
