int32 __stdcall RFmxWLAN_Commit (niRFmxInstrHandle instrumentHandle, char selectorString[]);
Commits settings to the hardware. Calling this function is optional. RFmxWLAN commits settings to the hardware when you call the RFmxWLAN_Initiate function.
| Input | ||
|---|---|---|
| Name | Type | Description |
| instrumentHandle | niRFmxInstrHandle | Specifies the instrument session. The RFmx driver obtains this parameter from the RFmxWLAN_Initialize function. |
| selectorString | char[] | Specifies a selector string comprising of the signal name. If you do not specify the signal name, the default signal instance is used. Example: "" "signal::sig1" You can use the RFmxWLAN_BuildSignalString function to build the selector string. |
| Name | Type | Description |
|---|---|---|
| status | int32 | Returns the status code of this operation. The status code either indicates success or describes an error or warning condition. Examine the status code from each call to an RFmx function to determine if an error has occurred. To obtain a text description of the status code and additional information about the error condition, call the RFmxWLAN_GetError function. The general meaning of the status code is as follows: |
| Value | Meaning |
|---|---|
| 0 | Success |
| Positive Values | Warnings |
| Negative Values | Errors |
int32 __stdcall RFmxWLAN_ResetToDefault (niRFmxInstrHandle instrumentHandle, char selectorString[]);
Resets a signal to the default values.

int32 __stdcall RFmxWLAN_WaitForAcquisitionComplete (niRFmxInstrHandle instrumentHandle, float64 timeout);
Waits and blocks the data flow until the acquisition is complete. This function is typically called after a specific initiate function.
This function is a wrapper over the RFmx Instruments API, and calls the RFmxInstr_WaitForAcquisitionComplete function.

| Name | Type | Description |
| instrumentHandle | niRFmxInstrHandle | Specifies the instrument session. The RFmx driver obtains this parameter from the RFmxWLAN_Initialize function. |
| timeout | float64 | Specifies the timeout, in seconds, for fetching the specified measurement. Set this value to an appropriate time, longer than expected for fetching the measurement. A value of -1 specifies that the function waits until the measurement is complete. |

| Name | Type | Description |
| instrumentHandle | niRFmxInstrHandle | Specifies the instrument session. The RFmx driver obtains this parameter from the RFmxWLAN_Initialize function. |
| selectorString | char[] | Specifies a selector string comprising of the signal name and result name. If you do not specify the signal name, the default signal instance is used. If you do not specify the result name, the default result instance is used. Example: "" "signal::sig1" "result::r1" "signal::sig1/result::r1" You can use the RFmxWLAN_BuildSignalString function to build the selector string. |
| timeout | float64 | Specifies the timeout, in seconds, for fetching the specified measurement. Set this value to an appropriate time, longer than expected for fetching the measurement. A value of -1 specifies that the function waits until the measurement is complete. |
