23 @deftypefn Replacement {const char*} lbasename (const char *@var{name})
25 Given a pointer to a string containing a typical pathname
26 (@samp{/usr/src/cmd/ls/ls.c} for example), returns a pointer to the
27 last component of the pathname (@samp{ls.c} in this case). The
28 returned pointer is guaranteed to lie within the original
29 string. This latter fact is not true of many vendor C
30 libraries, which return special strings or modify the passed
31 strings for particular input.
33 In particular, the empty string returns the same empty string,
34 and a path ending in @code{/} returns the empty string after it.
