/*

NAME
|
|
basename -- return pointer to last component of a pathname
|
|
|
|
SYNOPSIS
|
|
char *basename (const char *name)
|
|
|
|
DESCRIPTION
|
|
Given a pointer to a string containing a typical pathname
|
|
(/usr/src/cmd/ls/ls.c for example), returns a pointer to the
|
|
last component of the pathname ("ls.c" in this case).
|
|
|
|
BUGS
|
|
Presumes a UNIX or DOS/Windows style path with UNIX or DOS/Windows
|
|
style separators.
