NET_WAKE_SOURCE_MEDIA_CHANGE_PARAMETERS_INIT function (netwakesource.h)

  • Article

The NET_WAKE_SOURCE_MEDIA_CHANGE_PARAMETERS_INIT function initializes a NET_WAKE_SOURCE_MEDIA_CHANGE_PARAMETERS structure.

Syntax

void NET_WAKE_SOURCE_MEDIA_CHANGE_PARAMETERS_INIT(
  [_Out_] NET_WAKE_SOURCE_MEDIA_CHANGE_PARAMETERS *Parameters
);

Parameters

[_Out_] Parameters

A pointer to a driver-allocated NET_WAKE_SOURCE_MEDIA_CHANGE_PARAMETERS structure.

Return value

None

Remarks

This function zeroes out the memory of the NET_WAKE_SOURCE_MEDIA_CHANGE_PARAMETERS structure, then fills in the Size member. Client drivers must then call NetWakeSourceGetMediaChangeParameters to fill in the other members of the structure.

The client driver must only call NET_WAKE_SOURCE_MEDIA_CHANGE_PARAMETERS_INIT during a power transition, typically from its EVT_WDF_DEVICE_ARM_WAKE_FROM_SX, EVT_WDF_DEVICE_ARM_WAKE_FROM_S0, or EVT_NET_DEVICE_PREVIEW_WAKE_SOURCE callback function. Otherwise, the call results in a system bugcheck.

Requirements

Requirement Value
Minimum supported client Windows 10, version 2004
Target Platform Universal
Header netwakesource.h (include netadaptercx.h)
IRQL Any level as long as target memory is resident
