       attrib.

RESTRICTIONS

       ture, or the calling process must have write permissions to the NSG.

RETURN VALUES

       error.

ERRORS

       If the nsg_set() function fails, it sets errno to one of the following values for the specified condition: The  calling	process  does  not
       have write permission.  The attrib argument specifies an invalid address.  The nsg argument does not specify a valid NSG ID.
