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.

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.
