[gdal-dev] Catch a GDALOpen exception

[canduc17]

I have this incorrect code:
try
	{
	myDataset = (GDALDataset *) GDALOpen( "myimg", GA_ReadOnly );
	}
	catch(int n)
	{
		cout << "File not existent!" << endl;
                return 14;
	}


I would like to catch the exception thrown by GDALOpen if the file is not
existent and manage it in a way to return an integer that I want and not the
default 134.

How can I achieve this?

Thanks in advance!
