BASENAME(3)            FreeBSD Library Functions Manual            BASENAME(3)

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.

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.
