@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.
@end deftypefn
