-NAME
- lbasename -- return pointer to last component of a pathname
-
-SYNOPSIS
- char *lbasename (const char *name)
-
-DESCRIPTION
- Given a pointer to a string containing a typical pathname
- (/usr/src/cmd/ls/ls.c for example), returns a pointer to the
- last component of the pathname ("ls.c" in this case). The
- returned pointer is guaranteed to lie within the original
- string. This latter fact is not true of many vendor C
- libraries, which return special strings or modify the passed
- strings for particular input.
-
- In particular, the empty string returns the same empty string,
- and a path ending in '/' returns the empty string after it.
