remove - remove a file or directory
#include <stdio.h> int remove(const char *pathname);
remove() deletes a name from the file system. It calls unlink(2) for files, and rmdir(2) for directories. If the removed 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 is removed, but processes which have the object open may continue to use it.
On success, zero is returned. On error, -1 is returned, and errno is set appropriately.
C89, C99, 4.3BSD, POSIX.1-2001.
Under libc4 and libc5, remove() was an alias for unlink(2) (and hence would not remove directories).
Infelicities in the protocol underlying NFS can cause the unexpected disappearance of files which are still being used.
