 Name:         »Dsp_BlkBytes« - Bytewise data transfer to the DSP.

 Opcode:       124

 Syntax:       void Dsp_BlkBytes( void *data_in, int32_t size_in, void 
               *data_out, int32_t size_out );

 Description:  The function copies size_in unsigned bytes from the 
               buffer data_in to the DSP. After all data has been 
               transferred, the procedure waits until the data has 
               been processed. Then size_out 8-bit DSP-words are 
               copied back into the buffer data_out, irrespective of 
               how much data is actually present. If no data is to be 
               sent, one has to set size_in to zero. The same applies 
               for the receipt; in that case size_out is assigned 
               zero. size_in and size_out are limited to 64 kbyte. 
               Data is only exchanged when the DSP process is ready 
               for this.

 Return value: The function does not return a result.

 Availability: The function is available only on computers with the 
               DSP-56001 signal processor

 Group:        DSP programming
