Parameters

hContext

[in] A handle to the context to destroy. The display miniport driver's DxgkDdiCreateContext function previously returned this handle in the hContext member of the DXGKARG_CREATECONTEXT structure that the pCreateContext parameter of DxgkDdiCreateContext points to.

Return value
