RMDIR(2)                 DragonFly System Calls Manual                RMDIR(2)


rmdir -- remove a directory file


Standard C Library (libc, -lc)


#include <unistd.h> int rmdir(const char *path);


Rmdir() removes a directory file whose name is given by path. The direc- tory must not have any entries other than `.' and `..'.


The rmdir() function returns the value 0 if successful; otherwise the value -1 is returned and the global variable errno is set to indicate the error.


The named file is removed unless: [ENOTDIR] A component of the path is not a directory. [ENAMETOOLONG] A component of a pathname exceeded 255 characters, or an entire path name exceeded 1023 characters. [ENOENT] The named directory does not exist. [ELOOP] Too many symbolic links were encountered in translat- ing the pathname. [ENOTEMPTY] The named directory contains files other than `.' and `..' in it. [EACCES] Search permission is denied for a component of the path prefix. [EACCES] Write permission is denied on the directory containing the link to be removed. [EPERM] The directory containing the directory to be removed is marked sticky, and neither the containing directory nor the directory to be removed are owned by the effective user ID. [EINVAL] The last component of the path is `.' or `..'. [EBUSY] The directory to be removed is the mount point for a mounted file system. [EIO] An I/O error occurred while deleting the directory entry or deallocating the inode. [EROFS] The directory entry to be removed resides on a read- only file system. [EFAULT] Path points outside the process's allocated address space.
