Detailed Description

Represents defragmentation process in progress.

You can create this object using Allocator::BeginDefragmentation (for default pools) or Pool::BeginDefragmentation (for a custom pool).

Member Function Documentation

HRESULT D3D12MA::DefragmentationContext::BeginPass ( DEFRAGMENTATION_PASS_MOVE_INFO * pPassInfo )

Starts single defragmentation pass.

Parameters

[out] pPassInfo Computed informations for current pass.

Returns

S_OK if no more moves are possible. Then you can omit call to DefragmentationContext::EndPass() and simply end whole defragmentation.
S_FALSE if there are pending moves returned in pPassInfo. You need to perform them, call DefragmentationContext::EndPass(), and then preferably try another pass with DefragmentationContext::BeginPass().

HRESULT D3D12MA::DefragmentationContext::EndPass ( DEFRAGMENTATION_PASS_MOVE_INFO * pPassInfo )

Ends single defragmentation pass.

Parameters

pPassInfo Computed informations for current pass filled by DefragmentationContext::BeginPass() and possibly modified by you.

Returns: Returns S_OK if no more moves are possible or S_FALSE if more defragmentations are possible.

Ends incremental defragmentation pass and commits all defragmentation moves from pPassInfo. After this call:

Allocation at pPassInfo[i].pSrcAllocation that had pPassInfo[i].Operation == DEFRAGMENTATION_MOVE_OPERATION_COPY (which is the default) will be pointing to the new destination place.
Allocation at pPassInfo[i].pSrcAllocation that had pPassInfo[i].operation == DEFRAGMENTATION_MOVE_OPERATION_DESTROY will be released.

If no more moves are possible you can end whole defragmentation.
