PPoll — parallel poll devices

Synopsis

#include <gpib/ib.h>
void PPoll(board_desc,  
 result); 
int board_desc;
short *result;
 

Description

PPoll() is similar to the traditional API function ibrpp(). It causes the interface board to perform a parallel poll, and stores the parallel poll byte in the location specified by result. Bits 0 to 7 of the parallel poll byte correspond to the dio lines 1 to 8, with a 1 indicating the corresponding dio line is asserted. The devices on the bus you wish to poll should be configured beforehand with PPollConfig(). The board must be controller-in-charge to perform a parallel poll.
