NAMErmdir - delete a directory
DESCRIPTIONrmdir() deletes a directory, which must be empty.
RETURN VALUEOn success, zero is returned. On error, -1 is returned, and errnois set appropriately.
- Write access to the directory containing pathnamewas not allowed, or one of the directories in the path prefix of pathnamedid not allow search permission. (See also path_resolution(7).
- pathnameis currently in use by the system or some process that prevents its removal. On Linux, this means pathnameis currently used as a mount point or is the root directory of the calling process.
- pathname points outside your accessible address space.
- pathnamehas .as last component.
- Too many symbolic links were encountered in resolving pathname.
- pathname was too long.
- A directory component in pathnamedoes not exist or is a dangling symbolic link.
- Insufficient kernel memory was available.
- pathname, or a component used as a directory in pathname, is not, in fact, a directory.
- pathnamecontains entries other than . and .. ; or, pathnamehas ..as its final component. POSIX.1 also allows EEXISTfor this condition.
- The directory containing pathnamehas 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_FOWNERcapability).
- The filesystem containing pathnamedoes not support the removal of directories.
- pathnamerefers to a directory on a read-only filesystem.
CONFORMING TOPOSIX.1-2001, POSIX.1-2008, SVr4, 4.3BSD.
BUGSInfelicities in the protocol underlying NFS can cause the unexpected disappearance of directories which are still being used.
