Reading Data in Background while Playing Sound

Sample Description

In order to read data while playing back sound, use the ::criFsLoader_Load function in CRI File System.

Some Cue must be adjusted so that sound does not break by centralizing file I/O flow rate in order to perform streaming playback.

Since CRI Atom uses CRI File System for accessing files, application can easily achieve file I/O flow rate management by using functions in CRI File System for reading data.

CriFsLoaderHn loader;
CriFsLoaderStatus loader_status;
    /* Issue loading request */
    criFsLoader_Load(loader, NULL, FILE, 0, file_size, buf, buf_size);
    /* Application's main loop */
    for(;;) {
        /* Wait for V-synchronization */
        criFwSys_WaitVsync();
        /* Server processing */
        criAtomEx_ExecuteMain();
    
        /* Get CriFsLoader status */
        criFsLoader_GetStatus(loader, &loader_status);
        if (loader_status == CRIFSLOADER_STATUS_COMPLETE) {
            /* Post-loading task */
        }
    }
