SendIFC
Clears the GPIB bus by asserting the IFC (Interface Clear) line.
Syntax
C SendIFC(int board)
Parameters
board is an integer which identifies the GPIB board to be used for this operation. In most
applications, this value is 0.
Returns
ibsta will contain a 16-bit status word as described in Appendix B, IBSTA .
iberr will contain an error code, if an error occurred.
Usage Notes
This routine is used as part of the GPIB initialization procedure. When the system controller
asserts the IFC line, it unlistens and untalks all GPIB devices, forcing them to an idle state.
The system controller also becomes the Controller-In-Charge (CIC).
Example
Clears the GPIB bus from Board 0.
C SendIFC(0);
