The DrawInstanced function draws particular instances of nonindexed primitives.
unnamedParam1hDevice [in]
A handle to the display device (graphics context).
unnamedParam2VertexCountPerInstance [in]
The number of vertices per instance of the buffer that vertices are read from to draw the primitives.
unnamedParam3InstanceCount [in]
The number of instances of the buffer that vertices are read from to draw the primitives.
unnamedParam4StartVertexLocation [in]
The first vertex in the buffer that vertices are read from to draw the primitives.
unnamedParam5StartInstanceLocation [in]
The first instance of the buffer that vertices are read from to draw the primitives.
The driver can use the pfnSetErrorCb callback function to set an error code.
The driver should not encounter any error, except for D3DDDIERR_DEVICEREMOVED. Therefore, if the driver passes any error, except for D3DDDIERR_DEVICEREMOVED, in a call to the pfnSetErrorCb function, the Direct3D runtime will determine that the error is critical. Even if the device was removed, the driver is not required to return D3DDDIERR_DEVICEREMOVED; however, if device removal interfered with the operation of DrawInstanced (which typically should not happen), the driver can return D3DDDIERR_DEVICEREMOVED.
