Example Program

#include "dsc2.h"
int main(){
 vmeOpenDefaultWindows(); /* Map the VME bus memory (For Linux only.). */
 dsc2Init(0xe00000,0,1);  /* Base memory: Only last 2 HW switches are relevant, 
                             the rest are lost due to shift of address. */
                          /* Memory size per board. */
                          /* Number of boards. */
 dsc2Status(0,0);         /* Board number and flag which is not used. */
