Sample description

To load data while playing audio, use the ::criFsLoader_Load function of the CRI File System.

Some cues perform streaming playback, so you need to centralize the file I/O flow management and adjust it to prevent audio interruptions.

CRI Atom uses the CRI File System for file access processing, so applications can easily manage file I/O traffic by using CRI File System functions to read 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) {
            /* Processing when loading is complete */
        }
    }
