This method creates new custom processing block from function pointer. This lets the users pass frames between module boundaries for processing This is an infrastructure function aimed at middleware developers, and also used by provided blocks such as sync, colorizer, etc.. \param proc Processing function pointer to be applied to every frame entering the block \param context User context (can be anything or null) to be passed later as ctx param of the callback \param[out] error if non-null, receives any error that occurs during this call, otherwise, errors are ignored \return new processing block, to be released by rs2_delete_processing_block
