Example #1

File: android_Effect.cpp Project: MIPS/frameworks-wilhelm

//-----------------------------------------------------------------------------
android::status_t android_fx_getParam(const android::sp<android::AudioEffect>& pFx,
        int32_t param, uint32_t paramSizeMax, void *pValue, uint32_t valueSize)
{
    android::status_t status;
    uint32_t buf32[(paramSizeMax - 1) / sizeof(uint32_t) + 1];
    effect_param_t *p = (effect_param_t *)buf32;

    p->psize = sizeof(int32_t);
    *(int32_t *)p->data = param;
    p->vsize = valueSize;
    status = pFx->getParameter(p);
    if (android::NO_ERROR == status) {
        status = p->status;
        if (android::NO_ERROR == status) {
            memcpy(pValue, p->data + p->psize, p->vsize);
        }
    }

    return status;
