IOCTL_GNSS_RESPOND_NI IOCTL

Description

The IOCTL_GNSS_RESPOND_NI control code is used by the GNSS adapter to respond to an NI request that was asynchronously communicated to it by the GNSS driver through the resolution of an IOCTL_GNSS_LISTEN_NI request.

Parameters

Major code

Input buffer

A pointer to a GNSS_NI_RESPONSE structure.

Input buffer length

Set to sizeof(GNSS_NI_RESPONSE).

Output buffer

Set to NULL.

Output buffer length

Set to 0.

Input/output buffer

Input/output buffer length

Status block

Irp->IoStatus.Status is set to STATUS_SUCCESS if the request is successful. Otherwise, Status to the appropriate error condition as a NTSTATUS code.

Remarks

The driver sets one of the following NTSTATUS values to indicate result.

STATUS_SUCCESS, when the driver processed the users NI response information successfully.
Failed, when the driver does not process the users NI response information successfully.
Ignored, when the driver ignored the users NI response information.

GNSS driver notes

It is the GNSS driver’s responsibility to pass the user’s response, contained in the GNSS_NI_RESPONSE input structure to the NI. If the response is GNSS_Ni_UserResponseTimeout, the driver should determine the appropriate default response after time-out and send it to the SUPL server.
