NAME

       lfc_chown - change owner and group of a LFC directory/file in the name server

SYNOPSIS

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

       int lfc_chown (const char *path, uid_t new_uid, gid_t new_gid)

       int lfc_lchown (const char *path, uid_t new_uid, gid_t new_gid)

DESCRIPTION

       lfc_chown  sets  the owner and the group of a LFC directory/file in the name server to the
       numeric values in owner and group respectively.  If owner or group  is  specified  as  -1,
       lfc_chown() does not change the corresponding ID of the file.

       lfc_lchown  is  identical  to  lfc_chown except for symbolic links: it does not follow the
       link but changes the ownership of the link itself.

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

       To  change  the  owner  ID,  if the group ID does not change and if the caller and the new
       owner ID belong to that group, GRP_ADMIN privilege is needed, otherwise  the  caller  must
       have  ADMIN privilege in the Cupv database.  To change the group ID, the effective user ID
       of the process must match the owner ID of the file and the new group must be in  the  list
       of  groups  the  caller  belong  to  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 is a NULL pointer.

       ENOTDIR      A component of path prefix is not a directory.

       EINVAL       new_uid or new_gid is invalid.

       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.
