NAME¶

rmdir - delete a directory

LIBRARY¶

Standard C library (libc, -lc)

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 to indicate the error.

ERRORS¶

EACCES

Write access to the directory containing pathname was not allowed, or one of the directories in the path prefix of pathname did not allow search permission. (See also path_resolution(7).)

EBUSY

pathname is currently in use by the system or some process that prevents its removal. On Linux, this means pathname is currently used as a mount point or is the root directory of the calling process.

EFAULT

pathname points outside your accessible address space.

EINVAL

pathname has . as last component.

ELOOP

Too many symbolic links were encountered in resolving pathname.

ENAMETOOLONG

pathname was too long.

ENOENT

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

ENOMEM

Insufficient kernel memory was available.

ENOTDIR

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

ENOTEMPTY

pathname contains entries other than . and .. ; or, pathname has .. as its final component. POSIX.1 also allows EEXIST for this condition.

EPERM

The directory containing pathname has the sticky bit (S_ISVTX) set and the process's effective user ID is neither the user ID of the file to be deleted nor that of the directory containing it, and the process is not privileged (Linux: does not have the CAP_FOWNER capability).

EPERM

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

EROFS

pathname refers to a directory on a read-only filesystem.

STANDARDS¶

POSIX.1-2008.

HISTORY¶

POSIX.1-2001, SVr4, 4.3BSD.

BUGS¶

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