If that name + was the last link to a file and no processes have the file + open the file is deleted and the space it was using is + made available for reuse. + + If the name was the last link to a file but any processes + still have the file open the file will remain in existence + until the last file descriptor referring to it is closed. + + If the name referred to a symbolic link the link is + removed. + + If the name referred to a socket, fifo or device the name + for it is removed but processes which have the object open + may continue to use it. + +<h3>RETURN VALUE +</h3> On success, zero is returned.
