+@deftypefn Replacement {const char*} lbasename (const char *@var{name})
+
+Given a pointer to a string containing a typical pathname
+(@samp{/usr/src/cmd/ls/ls.c} for example), returns a pointer to the
+last component of the pathname (@samp{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 @code{/} returns the empty string after it.
