System Calls rmdir(2)
rmdir - remove a directory
int rmdir(const char *path);
The rmdir() function removes the directory named by the path
name pointed to by path. The directory must not have any
entries other than "." and "..".
If the directory's link count becomes zero and no process
has the directory open, the space occupied by the directory
is freed and the directory is no longer accessible. If one
or more processes have the directory open when the last link
is removed, the "." and ".." entries, if present, are
removed before rmdir() returns and no new entries may be
created in the directory, but the directory is not removed
until all references to the directory have been closed.
Upon successful completion rmdir() marks for update the
st_ctime and st_mtime fields of the parent directory.
Upon successful completion, 0 is returned. Otherwise, -1 is
returned, errno is set to indicate the error, and the named
directory is not changed.
The rmdir() function will fail if:
Search permission is denied for a component of the
path prefix; write permission is denied on the direc-
tory containing the directory to be removed; the
parent directory has the S_ISVTX variable set and is
not owned by the user; the directory is not owned by
the user and is not writable by the user; or the user
is not a super-user.
EBUSY The directory to be removed is the mount point for a
mounted file system.
The directory contains entries other than those for
"." and "..".
The path argument points to an illegal address.
