BASENAME(3)			   BSD Library Functions Manual 		      BASENAME(3)

     basename -- extract the base portion of a pathname

     #include <libgen.h>

     char *
     basename(const char *path);

     char *
     basename_r(const char *path, char *bname);

     The basename() function returns the last component from the pathname pointed to by path,
     deleting any trailing '/' characters.  If path consists entirely of '/' characters, a
     pointer to the string "/" is returned.  If path is a null pointer or the empty string, a
     pointer to the string "." is returned.

     The basename_r() variation accepts a buffer of at least MAXPATHLEN bytes in which to store
     the resulting component.

     The basename() function returns a pointer to internal storage space allocated on the first
     call that will be overwritten by subsequent calls.  basename_r() is therefore preferred for
     threaded applications.

     On successful completion, basename() and basename_r() return pointers to the last component
     of path.

     If they fail, 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:

     [ENAMETOOLONG]	The path component to be returned was larger than MAXPATHLEN.

     basename(1), dirname(1), dirname(3)

     The basename() function conforms to X/Open Portability Guide Issue 4, Version 2

     The basename() function first appeared in OpenBSD 2.2 and FreeBSD 4.2.

     Todd C. Miller

     basename() returns a pointer to internal static storage space that will be overwritten by
     subsequent calls.

     Other vendor implementations of basename() may modify the contents of the string passed to
     basename(); this should be taken into account when writing code which calls this function if
     portability is desired.
