S [in]

Type: SamplerState

A Sampler state. This is an object declared in an effect file that contains state assignments.

Location [in]

Type: float

The texture coordinates. The argument type is dependent on the texture-object type.

Texture-Object Type Parameter Type
Texture1D float
Texture1DArray, Texture2D float2
Texture2DArray, Texture3D, TextureCube float3
TextureCubeArray float4


CompareValue [in]

Type: float

A floating-point value to use as a comparison value.

Status [out]

Type: uint

The status of the operation. You can't access the status directly; instead, pass the status to the CheckAccessFullyMapped intrinsic function. CheckAccessFullyMapped returns TRUE if all values from the corresponding Sample, Gather, or Load operation accessed mapped tiles in a tiled resource. If any values were taken from an unmapped tile, CheckAccessFullyMapped returns FALSE.

Return value


The texture format, which is one of the typed values listed in DXGI_FORMAT.
