| @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. |
