NNS_SndUpdateDriverInfo

C Specification

#include <nnsys/snd.h>
BOOL NNS_SndUpdateDriverInfo( void );

Arguments

None.

Return Values

Returns whether the attempt to update the driver information succeeded or failed.

Description

Updates the sound driver's information.

The updated sound driver information can be obtained with NNS_SndReadDriverChannelInfo, NNS_SndPlayerReadDriverPlayerInfo, or NNS_SndPlayerReadDriverTrackInfo.

Even if the update fails, information at the time the sound driver information was last updated successfully can be obtained if update has succeeded at least once.

Note

Updating the sound driver's information involves communicating with ARM7. Accordingly, this function will continue to fail even if called repeatedly while processing does not occur on ARM7. Therefore, call this function about once per frame.

The update will always fail the first time this function is called.
