SND_SetTrackAllocatableChannel

Syntax

#include <nitro/snd.h>
void SND_SetTrackAllocatableChannel(
        int playerNo,
        u32 trackBitMask,
        u32 chBitFlag );

Arguments

playerNo The player number. Takes a value between 0 and 15.
trackBitMask This is the track bit mask. It designates which track to use.
chBitFlag This is an allocatable channel bit flag.

Return Values

None.

Description

Changes the allocatable channel with a track for the sequence currently playing on player number playerNo.

The track bit mask, trackBitMask, designates which track to use. Each bit expresses a track in descending order track 0 as the lowest bit. Operations are performed only on tracks with active bits.

chBitFlag designates the allocatable channels. The channels are represented in order, with the lowest bit representing channel 0. Operations are performed only on tracks with active bits. If a 0 is set in chBitFlag, allocation can be performed from all channels. This is the initially configured state.

Note

This function is an ARM7 reserved function. After this function is called, its processing will occur only after the command is issued with the SND_FlushCommand function.

If program execution must be synchronized with process completion, first use the SND_GetCurrentCommandTag function to obtain the command tag immediately after calling this function. Then, after the command is issued, use the command tag and call either the SND_IsFinishedCommandTag or SND_WaitForCommandProc function to confirm that processing has finished or to wait for it to complete.
