* oidcmp2 - compare any two objects identifiers
* SYNOPSIS
*
* \cs
* int oidcmp2
*     ( 
*     int       n1, 
*     OIDC_T *  idp1, 
*     int       n2, 
*     OIDC_T *  idp2 
*     )
* \ce
*
* DESCRIPTION
*
* This routine compares any two objects identifiers. This routine combines the 
* functions of both oidorder() and oidcmp().
*
* PARAMETERS
* \is
* \i <n1>
* Specify the length of the first object identifier
* \i <*idp1>
* Specify the first object identifier.
* \i <n2>
* Specify the length of the second object identifier.
* \i <*idp2>
* Specify the second object identifier.
* \ie
*
* RETURNS: If <idp1> is greater than <idp2>, this routine returns 1. If <idp1> 
* is less than <idp2>, it returns -1. If they are the same, it returns 0.
*
* ERRNO: N/A
*
* SEE ALSO: llist_cmp(), oidcmp(), oidorder()
