IDmaChannel::FreeBuffer method (portcls.h)
The FreeBuffer method frees the buffer that was allocated by the previous call to IDmaChannel::AllocateBuffer.
void FreeBuffer();
None
Because the buffer is automatically freed when the DMA-channel object is deleted, the FreeBuffer method is not typically used.
