* oidcmp - compare two objects identifiers of different lengths
* SYNOPSIS
*
* \cs
* int oidcmp
*     ( 
*     int        length_1, 
*     OIDC_T  *  oid_1, 
*     int        length_2, 
*     OIDC_T  *  oid_2 
*     )

*
* DESCRIPTION
*
* This routine compares two objects identifiers that may or may not have the 
* same length.
*
* PARAMETERS
* \is
* \i <length_1>
* Specify the length of the first object identifier.
* \i <*oid_1>
* Specify the first object identifier.
* \i <length_2>
* Specify the length of the second object identifier.
* \i <*oid_2>
* Specify the second object identifier.
* \ie
*
* RETURNS: If <oid1> is the same as <oid2>, this routine returns 1. Otherwise, 
* it returns 0.
*
* ERRNO: N/A
*
* SEE ALSO: llist_cmp(), oidcmp2(), oidorder()
