| 24 | |
| 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. |
| 32 | |
| 33 | In particular, the empty string returns the same empty string, |
| 34 | and a path ending in @code{/} returns the empty string after it. |
