NAME

       lfc_setacl - set LFC directory/file access control lists

SYNOPSIS

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

       int lfc_setacl (const char *path, int nentries, struct lfc_acl *acl)

DESCRIPTION

       lfc_setacl sets the Access Control List associated with a LFC directory/file.

       path   specifies the logical pathname relative to the current LFC directory or the full LFC pathname.

       nentries
              specifies the number of entries present in the buffer.

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

       struct lfc_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.
