NAME¶

dpns_chmod - change access mode of a DPNS directory/file in the name server

SYNOPSIS¶

#include <sys/types.h>
#include "dpns_api.h"

int dpns_chmod (const char *path, mode_t mode)

DESCRIPTION¶

dpns_chmod sets the access permission portion of the mode of a DPNS directory/file in the name server to the bit pattern in mode.

path

specifies the logical pathname relative to the current DPNS directory or the full DPNS pathname.

mode

is constructed by OR'ing the bits defined in <sys/stat.h> under Unix or "statbits.h" under Windows/NT:

The effective user ID of the process must match the owner of the file or the caller must have ADMIN privilege in the Cupv database. If a directory is writable and has the sticky bit set, files/directories within that directory can be removed or renamed only if:

RETURN VALUE¶

This routine returns 0 if the operation was successful or -1 if the operation failed. In the latter case, serrno is set appropriately.

ERRORS¶

EPERM

The effective user ID does not match the owner of the file and the caller does not have ADMIN privilege in the Cupv database.

ENOENT

The named file/directory does not exist or is a null pathname.

EACCES

Search permission is denied on a component of the path prefix.

EFAULT

path is a NULL pointer.

ENOTDIR

A component of path prefix is not a directory.

ENAMETOOLONG

The length of path exceeds CA_MAXPATHLEN or the length of a path component exceeds CA_MAXNAMELEN.

SENOSHOST

Host unknown.

SENOSSERV

Service unknown.

SECOMERR

Communication error.

ENSNACT
