* This function fills an (_arcs) array with OBJECT IDENTIFIER arcs

* unsigned long fixed_arcs[10]; // Try with fixed space first
* unsigned long *arcs = fixed_arcs;
* int arc_type_size = sizeof(fixed_arcs[0]); // sizeof(long)

* int count; // Real number of arcs.
* int i;
*
* count = OBJECT_IDENTIFIER_get_arcs(oid, arcs,
* arc_type_size, arc_slots);
* // If necessary, reallocate arcs array and try again.

* for(i = 0; i < count; i++)
* printf("%d\n", arcs[i]);
*
* // Avoid memory leak.
* if(arcs != fixed_arcs) free(arcs);

*
* RETURN VALUES:
* -1/EINVAL: Invalid arguments (oid is missing)
* -1/ERANGE: One or more arcs have value out of array cell type range.
* >=0: Number of arcs contained in the OBJECT IDENTIFIER
