Specifies how the CPU should respond when an application calls the ID3D11DeviceContext::Map method on a resource that is being used by the GPU.

Syntax

typedef enum D3D11_MAP_FLAG
{
    D3D11_MAP_FLAG_DO_NOT_WAIT = 0x100000L,
    D3D11_MAP_FLAG_ALLOW_USAGE_DEFAULT = 0x00200000L
} D3D11_MAP_FLAG;

Constants

Constant Description
D3D11_MAP_FLAG_DO_NOT_WAIT Specifies that ID3D11DeviceContext::Map should return DXGI_ERROR_WAS_STILL_DRAWING when the GPU blocks the CPU from accessing a resource. For more information about this error code, see DXGI_ERROR.
D3D11_MAP_FLAG_ALLOW_USAGE_DEFAULT Specifies that the CPU should allow using a resource that is being used by the GPU.
