Return Value
0 = Successful operation. Negative values are error codes and positive values are warnings. To get a description of the error, pass the error code to pipx40_error_message.
Description
This function establishes communications with the instrument.
Remarks
The values of the id_query and reset_instr parameters are ignored: instrument identity is always checked, and the instrument is always reset when it is opened. No error is given if these options are not specified in the function call.
If the initialisation function encounters an error, an error code return value will be sent, any valid sessions obtained by pipx40_init will be closed and the output parameter vi is set to zero (VI_NULL).
