/* 
 * int *INTARRAY  typemaps. 
 * These are input typemaps for mapping a Java int[] array to a C int array.
 * Note that as a Java array is used and thus passeed by reference, the C routine 
 * can return data to Java via the parameter.
 *
 * Example usage wrapping:
 *   void foo((int *INTARRAY, int INTARRAYSIZE);
 *  
 * Java usage:
 *   byte b[] = new byte[20];
 *   modulename.foo(b);
