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. | |
