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 ENOLINK The path argument points to a remote machine, and the connection to that machine is no longer active.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

NAME
rmdir - Removes a directory file SYNOPSIS
#include <unistd.h> int rmdir ( const char *path ); STANDARDS
Interfaces documented on this reference page conform to industry standards as follows: rmdir(): XSH5.0 Refer to the standards(5) reference page for more information about industry standards and associated tags. PARAMETERS
Specifies the directory pathname. The final component of the path parameter cannot be a symbolic link. DESCRIPTION
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 directory 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. How- ever, 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. RETURN VALUES
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. ERRORS
If the rmdir() function fails, the directory is not deleted and errno may be set to one of the following values: 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. The process does not have write access to the parent directory with respect to one of the system's access control policies. The directory is in use as either the mount point for a file system or the current directory of the process that issued the rmdir() function. The directory named by the path parameter is not empty. The path parameter is an invalid address. While reading from or writing to the file system, an I/O error occurred. 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. The directory named by the path parameter does not exist or is an empty string. A component of the path parameter is not a directory. The S_ISVTX flag is set on the parent directory of the directory to be removed, and the caller is not the file owner. The directory named by the path parameter resides on a read-only file system. [Tru64 UNIX] For NFS file access, if the rmdir() function fails, errno may also be set to one of the following values: The file position pointer associated with the filedes parameter was negative. Indicates either that the system file table is full, or that there are too many files currently open in the system. 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.
