SND_UnlockChannel

Syntax

#include <nitro/snd.h>
void SND_UnlockChannel( u32 chBitMask, u32 flags );

Arguments

chBitMask The channel bit mask. It specifies which channels to control.
flags Option flags. At the current time the flags are not used, so 0 is entered here.

Return Values

None.

Description

Unlocks channels that were locked with the SND_LockChannel function.

The channel bit mask chBitMask specifies which channels to control. The channels are represented in order, with the lowest bit representing channel 0. Only channels whose representative bits are standing are controlled.

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.
