Syntax

VOID Dsp_OutStream( data_out, block_size, num_blocks, blocks_done )
char *data_out;
LONG block_size;
LONG num_blocks;
LONG *blocks_done;

Function      Dsp_OutStream() transfers data from the DSP to
              a user-specified buffer using interrupts.

Opcode        100 (0x64)

Availability  Available only when bit #3 of the '_SND' cookie is set.

Parameters    This call transfers data from the DSP to the buffer pointed
              to by data_out via an interrupt handler. block_size
              specifies the number of DSP WORDs to be transferred and
              num_blocks specifies the number of blocks to transfer. The
              LONG pointed to by blocks_done will be constantly updated by
              the interrupt handler to indicate the number of blocks
              successfully transferred. The process is complete when
              blocks_done is equal to num_blocks.
