NAME

igpibppollconfig − configure a device’s parallel poll response

SYNOPSIS

 #include <sicl.h>
 int igpibppollconfig (id, val);
 INST id;
 int val;

DESCRIPTION

Igpibppollconfig configures a device’s parallel poll response.  This routine works only on interface sessions with active control. 
 
If val is -1, the device specified by id is disabled from generating parallel poll responses.  If val is > 0, the device is enabled to generate paralell poll responses.  In this case, the lower 4 bits of val correspond to:

­bit 3 Set the sense of the ppoll response.  A 1 in this bit means that an affirmative response means service request.  A 0 in this bit means that an affirmative response means no service request. 

­bits 2-0 A value from 0-7 specifying the GP-IB data line to respond on for parallel polls. 
 

RETURN VALUE

Igpibppollconfig returns 0 on success, or a non-zero error code otherwise. 

ERRORS

Igpibppollconfig fails under the following circumstances, and sets the return value to one of the following values:

­[I_ERR_BADID] The INST id is invalid. 

­[I_ERR_NOINTF] The interface is not active.
