RMDIR(2) System Calls RMDIR(2)


NAME


rmdir - remove a directory

SYNOPSIS


#include <unistd.h>

int rmdir(const char *path);


DESCRIPTION


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.

RETURN VALUES


Upon successful completion, 0 is returned. Otherwise, -1 is returned,
errno is set to indicate the error, and the named directory is not
changed.

ERRORS


The rmdir() function will fail if:

EACCES
Search permission is denied for a component of the path
prefix and {PRIV_FILE_DAC_SEARCH} is not asserted in the
effective set of the calling process

Write permission is denied on the directory containing
the directory to be removed and {PRIV_FILE_DAC_WRITE} is
not asserted.

The parent directory has the S_ISVTX variable set, is not
owned by the user, and {PRIV_FILE_OWNER} is not asserted.

The directory is not owned by the user and is not
writable by the user.


EBUSY
The directory to be removed is the mount point for a
mounted file system.


EEXIST
The directory contains entries other than those for "."
and "..".


EFAULT
The path argument points to an illegal address.


EINVAL
The directory to be removed is the current directory, or
the final component of path is ".".


EILSEQ
The path argument includes non-UTF8 characters and the
file system accepts only file names where all characters
are part of the UTF-8 character codeset.


EIO
An I/O error occurred while accessing the file system.


ELOOP
Too many symbolic links were encountered in translating
path.


ENAMETOOLONG
The length of the path argument exceeds PATH_MAX, or the
length of a path component exceeds NAME_MAX while
_POSIX_NO_TRUNC is in effect.


ENOENT
The named directory does not exist or is the null
pathname.


ENOLINK
The path argument points to a remote machine, and the
connection to that machine is no longer active.


ENOTDIR
A component of the path prefix is not a directory.


EROFS
The directory entry to be removed is part of a read-only
file system.
