BOOL NNS_SndArcLoadWaveArc( int waveArcNo, NNSSndHeapHandle heap );
Loads the waveform archive to the heap.
The memory necessary for loading is automatically allocated from the sound heap heap
with the NNS_SndHeapAlloc
function. If memory allocation fails, the process is interrupted, and FALSE
is returned.
The sound data already resident in memory is not loaded. Execution of the NNS_SndArcGetFileAddress
function will determine if the sound data is resident in memory. In addition, the NNS_SndArcSetFileAddress
function sets the address of the successfully loaded data.
If you want to limit the size of data that can be loaded at one time, use the NNS_SndArcSetLoadBlockSize
function to specify the load block size.
Use this function only for sound archives initialized using the NNS_SndArcInit
function. This function cannot be used with sound archives initialized using the NNS_SndArcInitOnMemory
function.
You can load waveforms individually by setting the s
option in the waveform archive section of the sound archive definition file. However, when the s
option is set, this function loads only the waveform archive header and the waveform table. (The waveform(s) themselves are loaded by use along with the NNS_SndArcLoadBank
function and similar functions.) Conversely, if you do not set the s
option, this function loads the entire waveform archive.
Waveform tables loaded when the s
option is set are used by the NITRO-Composer component to manage which waveforms have finished loading. The size of a waveform table increases by 32 bytes per every 4 waveforms, in direct proportion to the number of waveforms in the waveform archive.
