结构体指针用法

结构体指针用法：

struct MPEG4Config
{
    int nLocalFPS;
    int nLocalBitrate;
    int nRemoteFPS;
    int nRemoteBitrate;
    int nKeyFrameInterval;
    int w;
    int h;
};



void CMPEG4VideoDevice::SetConfig(void* pConfig)
{
    MPEG4Config* pMPEG4Config = (MPEG4Config*)pConfig;
    m_nLocalFPS = pMPEG4Config->nLocalFPS;
    m_nLocalBitrate = pMPEG4Config->nLocalBitrate;
    m_nRemoteFPS = pMPEG4Config->nRemoteFPS;
    m_nRemoteBitrate = pMPEG4Config->nRemoteBitrate;
    m_nKeyFrameInterval = pMPEG4Config->nKeyFrameInterval;
    m_nWidth = pMPEG4Config->w;
    m_nHeight = pMPEG4Config->h;
}



main（）

{。。。。。



            MPEG4Config newConfig;
            newConfig.nKeyFrameInterval = keyinternal;
            newConfig.nLocalBitrate = localBr;
            newConfig.nLocalFPS = localFps;
            newConfig.nRemoteBitrate = rBr;
            newConfig.nRemoteFPS = rFps;
            newConfig.w = w;
            newConfig.h = h;
            pVideoDevice->SetConfig((void*)(&newConfig));



}
