VideoPortReleaseBuffer function

Description

The VideoPortReleaseBuffer function is obsolete in Windows 2000 and later. In its place, video miniport drivers should instead use VideoPortFreePool.

VideoPortReleaseBuffer deallocates a block of paged pool memory.

Parameters

HwDeviceExtension [in]

Pointer to the miniport driver's device extension.

Buffer [in]

Specifies the address of the block of pool memory being deallocated.

Return value

None

Remarks

This function releases memory allocated by VideoPortAllocateBuffer. A miniport driver must not access the memory block to which Buffer points after it has been freed.
