basename
basename(3C) Standard C Library Functions basename(3C) NAME
basename - return the last element of a path name SYNOPSIS
#include <libgen.h> char *basename(char *path); DESCRIPTION
The basename() function takes the pathname pointed to by path and returns a pointer to the final component of the pathname, deleting any trailing '/' characters. If the string consists entirely of the '/' character, basename() returns a pointer to the string "/" . If path is a null pointer or points to an empty string, basename() returns a pointer to the string "." . RETURN VALUES
The basename() function returns a pointer to the final component of path. USAGE
The basename() function may modify the string pointed to by path, and may return a pointer to static storage that may then be overwritten by a subsequent call to basename(). When compiling multithreaded applications, the _REENTRANT flag must be defined on the compile line. This flag should only be used in mul- tithreaded applications. EXAMPLES
