NAME

iblines - monitor bus lines (board)

SYNOPSIS

#include <gpib/ib.h>

int iblines(int ud , short * line_status );

DESCRIPTION

iblines() is used to obtain the status of the control and handshaking bus lines of the bus. The board used to monitor the bus is specified by the ud argument, and the status of the various bus lines are written to the location specified by line_status .

Some older chips are not capable of reporting the status of the bus lines, so each line has two corresponding bits in line_status . One bit indicates if the board can monitor the line, and the other bit indicates the line's state. The meaning of the line_status bits are as follows:
