s32 KPADRead( s32 chan, KPADStatus samplingBufs[], u32 length );

Arguments

chan	one of the WPAD_CHANn values.

Description

This function reads data in the KPADStatus structure type for each controller channel. We have assumed that this function will be called for each game frame. The buffer specified by the argument stores, from newest to oldest, the data sampled from the time of the previous call to the time of the current call. (In other words, the newest data is always stored at the beginning of the buffer.) However, button information references only the most recent value when KPADRead is called, and this value is copied to all current sampling buffers.
