SYNOPSIS

#include <sys/types.h>

#include "dpns_api.h"

int dpns_setacl (const char *path, int nentries, struct dpns_acl *acl)

DESCRIPTION

dpns_setacl sets the Access Control List associated with a DPNS directory/file.

path

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

nentries

specifies the number of entries present in the buffer.

acl

is a pointer to an array of dpns_acl structures provided by the application.

struct dpns_acl {
        unsigned char   a_type;
        int             a_id;
        unsigned char   a_perm;
};

a_type

is the ACL type: CNS_ACL_USER_OBJ, CNS_ACL_USER, CNS_ACL_GROUP_OBJ, CNS_ACL_GROUP, CNS_ACL_MASK or CNS_ACL_OTHER. Types for default entries are obtained by OR'ing the flag CNS_ACL_DEFAULT with one of the above types.

a_id

is the user or group numeric id.

a_perm

is the access permission in numeric form obtained by OR'ing some of the bits S_IROTH, S_IWOTH, S_IXOTH.

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.

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 or acl is a NULL pointer.

ENOTDIR

A component of path prefix is not a directory.

EINVAL

nentries is not greater than zero or is greater than CA_MAXACLENTRIES or the ACL entries are not valid.

ENOSPC

The name server database is full.

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

Name server is not running or is being shutdown.
