最新版GDAL 读取shape文件

[_BetterZ]

项目需求，用了新版的GDAL，以前的读写shape方法：
OGRSFDriverRegistrar * pRegistrar = OGRSFDriverRegistrar::GetRegistrar();
OGRSFDriver *pOGRDriver = pRegistrar->GetDriverByName("ESRI Shapefile");
OGRDataSource * pOGRDataSource = pOGRDriver->Open( shpFileName,TRUE );
OGRLayer *pLayer =pOGRDataSource->GetLayer(0);

pLayer->ResetReading();
int count = pLayer->GetFeatureCount();
for (int i = 0; i < count; i++)
{
OGRFeature * pFeature = pLayer->GetFeature(i);
……
} 现在用不了了，因为GetDriverByName() 这个函数返回的GDALDriver，现在我是不知道怎么获取OGRSFLayer了，求助各位大神了。

新版的ogrsf_frmts.h/好像是2015年的
