NAME
dirname -- report the parent directory name of a file pathname
LIBRARY
Standard C Library (libc, -lc)
SYNOPSIS
#include <libgen.h> char * dirname(char *path);
DESCRIPTION
The dirname() function takes a pointer to a character string that con- tains a pathname, path, and returns a pointer to a string that is a path- name 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 ``.''.
RETURN VALUES
The dirname() function returns a pointer to a string that is the parent directory of path.

BUGS
If the length of the result is longer than 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''). NetBSD 8.1 May 10, 2008 NetBSD 8.1
