dirname
(char
*path);
dirname
() function takes a pointer to a character
string that contains a pathname, path, and returns a
pointer to a string that is a pathname of the parent directory of
path. Trailing ‘/’ characters in
path are not counted as part of the path.
If path does not contain a
‘/’, then dirname
() returns a pointer
to the string “.”.
If path is a null pointer or points to an
empty string, dirname
() returns a pointer to the
string “.”.
dirname
() function returns a pointer to a string
that is the parent directory of path.
PATH_MAX
bytes (including the terminating nul), the result will be truncated.
The dirname
() function returns a pointer
to static storage that may be overwritten by subsequent calls to
dirname
(). This is not strictly a bug; it is
explicitly allowed by IEEE Std 1003.1-2001
(“POSIX.1”).
