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.
