sync_volume_np(3) [osx man page]

SYNC_VOLUME_NP(3)					   BSD Library Functions Manual 					 SYNC_VOLUME_NP(3)

NAME
sync_volume_np -- Sync a mounted filesystem LIBRARY
Standard C Library (libc, -lc) SYNOPSIS
#include <unistd.h> int sync_volume_np(const char *path, int flags); int fsync_volume_np(int fd, int flags); DESCRIPTION
The sync_volume_np() function causes data and metadata on the filesystem containing path to be synced to disk; this may be any file or direc- tory on that filesystem. The fsync_volume_np() does the same thing, but using an open file descriptor for that filesystem. Both functions take a flags parameter, with the currently-defined options: SYNC_VOLUME_FULLSYNC Request that the data and metadata be written to the disk hardware; if not set, then the hardware may keep it in cache. SYNC_VOLUME_WAIT Wait for the data and metadata to be written; if not set, then it will return when the requests have been made. RETURN VALUES
Both functions return 0 on success, and a non-zero error code on error. ERRORS
The fsync_volume_np() function may return EBADF if the fd parameter is not a valid, open file descriptor. The sync_volume_np() function may return errors if: [EACCES] Search permission is denied for a component of the path prefix. [EIO] An I/O error occurs while reading from or writing to the file system. [ELOOP] Too many symbolic links are encountered in translating the pathname. This is taken to be indicative of a looping symbolic link. [ENAMETOOLONG] A component of a pathname exceeds {NAME_MAX} characters, or an entire path name exceeds {PATH_MAX} characters. [ENOENT] The named file does not exist. [ENOTDIR] A component of the path prefix is not a directory. BSD

NAME
rmdir -- remove a directory file SYNOPSIS
#include <unistd.h> int rmdir(const char *path); DESCRIPTION
Rmdir() removes a directory file whose name is given by path. The directory must not have any entries other than '.' and '..'. RETURN VALUES
A 0 is returned if the remove succeeds; otherwise a -1 is returned and an error code is stored in the global location errno. ERRORS
The named file is removed unless: [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. [EBUSY] The directory to be removed is the mount point for a mounted file system. [EFAULT] Path points outside the process's allocated address space. [EIO] An I/O error occurs while deleting the directory entry or deallocating the inode. [ELOOP] Too many symbolic links are encountered in translating the pathname. This is taken to be indicative of a looping symbolic link. [ENAMETOOLONG] A component of a pathname (possibly expanded by a symbolic link) exceeds {NAME_MAX} characters, or an entire path name exceeded {PATH_MAX} characters. [ENOENT] The named directory does not exist. [ENOTDIR] A component of the path is not a directory. [ENOTEMPTY] The named directory contains files other than '.' and '..' in it. [EPERM] The directory containing the directory to be removed is marked sticky, and neither the containing directory nor the direc- tory to be removed are owned by the effective user ID. [EROFS] The directory entry to be removed resides on a read-only file system. SEE ALSO
mkdir(2), unlink(2) HISTORY
The rmdir() function call appeared in 4.2BSD. 4.2 Berkeley Distribution June 4, 1993 4.2 Berkeley Distribution
