Function Documentation

char* dirname

(

CONST char *

path

)

Extract the directory part of a given pathname.

This is the converse of basename().

Parameters:

path	Pointer to the pathname.

Returns:

A pointer to the parent directory of the pathname. Any trailing slash is not counted as part of the directory name. If the specified pathname is a null pointer, an empty string, or contains no slash character, then a single dot is returned. On failures, a NULL pointer is returned and the global variable errno is set to indicate the error.
