PEPCALLBACKPOWERONCRASHDUMPDEVICE callback function (pepfx.h)

The PowerOnDumpDeviceCallback callback routine turns on the crash-dump device.

Syntax

PEPCALLBACKPOWERONCRASHDUMPDEVICE Pepcallbackpoweroncrashdumpdevice;

BOOLEAN Pepcallbackpoweroncrashdumpdevice(
  [in] PPEP_CRASHDUMP_INFORMATION CrashdumpInformation
)
{...}

Parameters

[in] CrashdumpInformation

A pointer to a PEP_CRASHDUMP_INFORMATION structure that contains information about the crash-dump device.

Return value

This routine returns TRUE if it succeeds in turning on power to the crash-dump device. Otherwise, it returns FALSE.

Remarks

This routine is implemented by the platform extension plug-in (PEP). The routine handles requests from the Windows kernel to turn on the crash-dump device so that a crash dump can be saved to disk.

The PEP registers its PowerOnDumpDeviceCallback routine in response to a PEP_DPM_REGISTER_CRASHDUMP_DEVICE notification from the Windows power management framework (PoFx).

The PowerOnDumpDeviceCallback routine is called at IRQL = HIGH_LEVEL with interrupts disabled. Thus, this routine cannot use timers, events, or any synchronization primitives other than spin locks.
