dirname —
#include <libgen.h>
char *
  
  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”).
