SendCmds

Send GPIB commands.

Syntax

C SendCmds (int board, char commands[],

unsigned long count)

Parameters

board is an integer which identifies the GPIB board to be used for this operation. In most

applications, this value is 0.

commands is a string containing the GPIB command bytes to be sent.

count specifies the maximum number of command bytes which are to be sent.

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 useful in situations where specialized GPIB command sequences are called for.

Example

The GPIB board (at 0) simultaneously triggers the GPIB devices at addresses 8 and 9 and

quickly puts them in local mode.
