* oidorder - compare two object identifiers of the same length
* SYNOPSIS
*
* \cs
* int oidorder
*     ( 
*     OIDC_T  *  oid_1, 
*     OIDC_T  *  oid_2, 
*     int        length 
*     )
* \ce
*
* DESCRIPTION
*
* This routine compares two object identifiers of the same length to determine 
* which is greater.
*
* PARAMETERS
* \is
* \i <*oid_1>
* Specify the first object identifier.
* \i <*oid_2>
* Specify the second object identifier.
* \i <length>
* Specify the length of the object identifiers.
* \ie
*
* RETURNS: If <oid_1> is greater than <oid_2>, this routine returns 1. If 
* <oid_1> is less than <oid_2>, it returns -1. If they are the same, it returns 
* 0.
*
* ERRNO: N/A
*
* SEE ALSO: llist_cmp(), oidcmp(), oidcmp2()
