NAME
     basename -- extract the base portion of a pathname

SYNOPSIS
     #include <libgen.h>

     char *
     basename(char *path);

DESCRIPTION
     The basename() function returns the last component	from the pathname
     pointed to	by path, deleting any trailing `/' characters.

IMPLEMENTATION NOTES
     This implementation of basename() uses the	buffer provided	by the caller
     to	store the resulting pathname component.	 Other vendor implementations
     may return	a pointer to internal storage space instead.  The advantage of
     the former	approach is that it ensures thread-safety, while also placing
     no	upper limit on the supported length of the pathname.

RETURN VALUES
     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.  Otherwise, it	returns	a pointer to the last
     component of path.

SEE ALSO
     basename(1), dirname(1), dirname(3)

STANDARDS
     The basename() function conforms to X/Open	Portability Guide Issue	4,
     Version 2 ("XPG4.2").

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

     In	FreeBSD	12.0, this function was	reimplemented to store its result in
     the provided input	buffer.	 There is no longer any	need to	use the
     basename_r() function.
