DIRNAME(3) OpenBSD Programmer's Manual DIRNAME(3)
NAME
dirname - extract the directory portition of a pathname
SYNOPSIS
#include <libgen.h>
char *
dirname(const char *path);
DESCRIPTION
The dirname() function is the converse of basename(3); it returns a
pointer to the parent directory of the pathname pointed to by path. Any
trailing `/' characters are not counted as part of the directory name.
If path is a null pointer, the empty string, or contains no `/' charac-
ters, dirname() returns a pointer to the string ".", signifying the cur-
rent directory.
RETURN VALUES
On successful completion, dirname() returns a pointer to the parent di-
rectory of path.
If dirname() fails, a null pointer is returned and the global variable
errno is set to indicate the error.
ERRORS
The following error codes may be set in errno:
[ENAMETOOLONG]
The path component to be returned was larger than
MAXPATHLEN.
WARNINGS
dirname() returns a pointer to internal static storage space that will be
overwritten by subsequent calls (each function has its own separate stor-
age).
Other vendor implementations of dirname() may modify the contents of the
string passed to dirname(); this should be taken into account when writ-
ing code which calls this function if portability is desired.
SEE ALSO
basename(1), dirname(1), basename(3)
STANDARDS
The dirname() function conforms to X/Open Portability Guide Issue 4.2
(``XPG4.2'').
HISTORY
The dirname() function first appeared in OpenBSD 2.2.
