DIRNAME(3)                OpenBSD Programmer's Manual               DIRNAME(3)

     dirname - extract the directory portition of a pathname

     #include <libgen.h>

     char *
     dirname(const char *path);

     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.

     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.

     The following error codes may be set in errno:

                   The path component to be returned was larger than

     dirname() returns a pointer to internal static storage space that will be
     overwritten by subsequent calls (each function has its own separate stor-

     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.

     The dirname() function conforms to X/Open Portability Guide Issue 4.2

     The dirname() function first appeared in OpenBSD 2.2.
