Nameunlink - delete a name and possibly the file it refers to
int unlink(const char *pathname);
Descriptionunlink deletes a name from the filesystem. 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.
Return ValueOn success, zero is returned. On error, -1 is returned, and errno is set appropriately.
