NAME
       rmdir - delete a directory

SYNOPSIS
       #include <unistd.h>

       int rmdir(const char *pathname);

DESCRIPTION
       rmdir deletes a directory, which must be empty.

RETURN VALUE
       On success, zero is returned.  On error, -1 is returned, and errno is set appropriately.

ERRORS
       EPERM  The filesystem containing pathname does not support the removal of directories.

       EFAULT pathname points outside your accessible address space.

       EACCES Write  access  to  the  directory  containing pathname was not allowed for the process's effective uid, or one of the directories in
	      pathname did not allow search (execute) permission.

       EPERM  The directory containing pathname has the sticky-bit (S_ISVTX) set and the process's effective uid is neither the uid of the file to
	      be deleted nor that of the directory containing it.

       ENAMETOOLONG
	      pathname was too long.

       ENOENT A directory component in pathname does not exist or is a dangling symbolic link.

       ENOTDIR
	      pathname, or a component used as a directory in pathname, is not, in fact, a directory.

       ENOTEMPTY
	      pathname contains entries other than . and .. .

       EBUSY  pathname is the current working directory or root directory of some process.

       ENOMEM Insufficient kernel memory was available.

       EROFS  pathname refers to a file on a read-only filesystem.

       ELOOP  Too many symbolic links were encountered in resolving pathname.

CONFORMING TO
       SVr4, SVID, POSIX, BSD 4.3

BUGS
       Infelicities in the protocol underlying NFS can cause the unexpected disappearance of directories which are still being used.
