NAME

       ibrpp - perform a parallel poll (board or device)

SYNOPSIS

       #include <gpib/ib.h>

       int ibrpp(int ud, char *ppoll_result);

DESCRIPTION

       ibrpp() causes the interface board to perform a parallel poll, and stores the resulting parallel poll
       byte in the location specified by ppoll_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 ibppc(). The board which performs the parallel poll
       must be controller-in-charge, and is specified by the descriptor ud. If ud is a device descriptor instead
       of a board descriptor, the device's access board performs the parallel poll.

RETURN VALUE

       The value of ibsta is returned.
