NAME
       dpns_setacl - set DPNS directory/file access control lists

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.
