rmdir - Removes a directory file
int rmdir (
const char *path );

try standards and associated tags.
path Specifies the directory pathname. The final component of the
path parameter cannot be a symbolic link.
The rmdir() function removes the directory specified by the path parameter.
The directory is removed only if it is an empty directory.
For the rmdir() function to execute successfully, the calling process must
have write access to the parent directory of the path parameter with
respect to all of the system's access control policies.
If the directory's link count becomes 0 (zero) and no process has the
directory open, the space occupied by the directory is freed and the direc-
tory is no longer accessible. If one or more processes have the directory
open when the last link is removed, the . (dot) and .. (dot-dot) entries,
if present, are removed before the rmdir() function returns, and no new
entries may be created in the directory. However, the directory is not
removed until all references to the directory have been closed.
Upon successful completion, the rmdir() function marks the st_ctime and
st_mtime fields of the parent directory for update.
Upon successful completion, the rmdir() function returns a value of 0
(zero). If the rmdir() function fails, a value of -1 is returned and errno
is set to indicate the error.
If the rmdir() function fails, the directory is not deleted and errno may
be set to one of the following values:
[EACCES] Search permission is denied on a component of the path parameter,
or write permission is denied on the parent directory of the
directory to be removed.
[EACCES] The process does not have write access to the parent directory
with respect to one of the system's access control policies.
[EBUSY] The directory is in use as either the mount point for a file sys-
tem or the current directory of the process that issued the
[EEXIST] The directory named by the path parameter is not empty.
[EFAULT] The path parameter is an invalid address.
[EIO] While reading from or writing to the file system, an I/O error
[ELOOP] Too many links were encountered in translating path.
The length of the path parameter exceeds PATH_MAX, or a pathname
component is longer than NAME_MAX.
[ENOENT] The directory named by the path parameter does not exist or is an
[ENOTDIR] A component of the path parameter is not a directory.
[EPERM] The S_ISVTX flag is set on the parent directory of the directory
to be removed, and the caller is not the file owner.
[EROFS] The directory named by the path parameter resides on a read-only
[Tru64 UNIX] For NFS file access, if the rmdir() function fails, errno may
also be set to one of the following values:
[EINVAL] The file position pointer associated with the filedes parameter
[ENFILE] Indicates either that the system file table is full, or that
there are too many files currently open in the system.
[ESTALE] Indicates a stale NFS file handle. An opened file was deleted by
the server or another client; a client cannot open a file because
the server has unmounted or unexported the remote directory; or
the directory that contains an opened file was either unmounted
or unexported by the server.
