IBONL

Enables/Disables a device/interface board for operation.

Syntax

C ibonl (int boarddev, int online)

Parameters

boarddev is an integer containing the device/board handle.

online defines whether the device/board is to be enabled/disabled. If online is non-zero,

the device/board is enabled for operation (placed on-line). This restores the board/device to

its default settings. Otherwise, the board/device is placed off-line.

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

When a device is placed off-line, it is "closed". This means that in order to perform any other

operations with this device, you will need to re-open it by calling the

ibfind or ibdev

routine.

Example

This example restores the configuration of a device at PAD 1.

C int Dev;

Dev = ibdev (0,1,0,13,1,0);

ibonl (Dev, 1);
