The CreateSampler function creates a sampler.
unnamedParam1hDevice [in]
A handle to the display device (graphics context).
unnamedParam2pSamplerDesc [in]
A pointer to a D3D10_DDI_SAMPLER_DESC structure that describes the parameters that the user-mode display driver uses to create a sampler.
unnamedParam3hSampler [in]
A handle to the driver's private data for the sampler. The driver returns the size, in bytes, of the memory region that the Microsoft Direct3D runtime must allocate for the private data from a call to the driver's CalcPrivateSamplerSize function. The handle is really just a pointer to a region of memory, the size of which the driver requested. The driver uses this region of memory to store internal data structures that are related to its sampler object.
unnamedParam4hRTSampler [in]
A handle to the sampler that the driver should use anytime it calls back into the Direct3D runtime.
The driver can use the pfnSetErrorCb callback function to set an error code.
The driver can pass E_OUTOFMEMORY (if the driver runs out of memory) or D3DDDIERR_DEVICEREMOVED (if the device has been removed) in a call to the pfnSetErrorCb function. The Direct3D runtime will determine that any other errors are critical. If the driver passes any errors, including D3DDDIERR_DEVICEREMOVED, the Direct3D runtime will determine that the handle is invalid; therefore, the runtime will not call the DestroySampler function to destroy the handle that the hSampler parameter specifies.
The user-mode display driver is not required to create more than 4,096 unique instances of sampler objects on a device at a time.
