osAiGetLength
Syntax#include <ultra64.h>
u32 osAiGetLength(void);
Explanation
The osAiGetStatus, osAiGetLength, osAiSetFrequency, and osAiSetNextBuffer routines provide basic control for the AI (audio interface).
This function (osAiGetLength) returns the number of bytes remaining in the current DMA buffer.
Notes
For hardware version 1.0, the audio DMA length register is only 15-bit long and thus supports a maximum transfer size of 32 Kbytes. In the final release, this register is extended to 18 bits to support a transfer of 256 Kbytes.
