int32 __stdcall RFmxBT_Close (niRFmxInstrHandle instrumentHandle, int32 forceDestroy);


Closes the RFmx session.

This function is a wrapper over the NI-RFmx Instruments API, and calls the RFmxInstr_Close function.


Name Type Description
instrumentHandle niRFmxInstrHandle Specifies the instrument session. The RFmx driver obtains this parameter from the RFmxBT_Initialize function.
forceDestroy int32 Specifies whether to destroy the NI-RFmx session.

RFMXBT_VAL_FALSE (0) Destroys the NI-RFmx session. Call the RFmxBT_Close function a number of times equal to the number of times you obtained a reference to the NI-RFmx session.
RFMXBT_VAL_TRUE (1) Destroys the NI-RFmx session. You do not have to call the RFmxBT_Close function multiple times. Destroying the NI-RFmx session invalidates all references to the session.
