@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.
