Set the target output buffers for the stream-output stage of the pipeline.
void SOSetTargets( UINT NumBuffers, ID3D11Buffer * const *ppSOTargets, const UINT *pOffsets );
The number of buffer to bind to the device. A maximum of four output buffers can be set. If less than four are defined by the call, the remaining buffer slots are set to NULL. See Remarks.
Type: const UINT*
Array of offsets to the output buffers from ppSOTargets, one offset for each buffer. The offset values must be in bytes.
An offset of -1 will cause the stream output buffer to be appended, continuing after the last location written to the buffer in a previous stream output pass.
Calling this method using a buffer that is currently bound for writing will effectively bind NULL instead because a buffer cannot be bound as both an input and an output at the same time.
The debug layer will generate a warning whenever a resource is prevented from being bound simultaneously as an input and an output, but this will not prevent invalid data from being used by the runtime.
The method will hold a reference to the interfaces passed in. This differs from the device state behavior in Direct3D 10.
