D3D12DDIARG_RESOURCE_BARRIER_0022 structure (d3d12umddi.h)

The D3D12DDIARG_RESOURCE_BARRIER_0022 structure contains the resource barrier parameters for the PFND3D12DDI_RESOURCEBARRIER_0022.

Syntax

typedef struct D3D12DDIARG_RESOURCE_BARRIER_0022 {
  D3D12DDI_RESOURCE_BARRIER_TYPE  Type;
  D3D12DDI_RESOURCE_BARRIER_FLAGS Flags;
  union {
    D3D12DDI_RESOURCE_TRANSITION_BARRIER_0003 Transition;
    D3D12DDI_RESOURCE_RANGED_BARRIER_0022     Ranged;

  };
} D3D12DDIARG_RESOURCE_BARRIER_0022;

Members

Type

The type of resource barrier as a D3D12DDI_RESOURCE_BARRIER_TYPE value. This member determines which barrier type to use in the union below.

Flags

A barrier flag as a D3D12DDI_RESOURCE_BARRIER_FLAGS value.

Transition

A D3D12DDI_RESOURCE_TRANSITION_BARRIER_0003 structure that describes the transition of subresources between different usages. This structure's members specify the before and after usages of the subresources.

Ranged

A D3D12DDI_RESOURCE_RANGED_BARRIER_0022 structure that describes a ranged barrier.

UAV

A D3D12DDI_RESOURCE_UAV_BARRIER structure that describes a resource in which all UAV accesses (reads or writes) must complete before any future UAV accesses (read or write) can begin.
