Belaid,

TestCapability() is actually an OGR method.  In GDAL we test for particular
capability related metadata items. In GDAL you could test for the Create()
method being supported with the following:

         if( GDALGetMetadataItem( hDriver, GDAL_DCAP_CREATE, NULL ) != NULL )
             ... we have Create support ...

Best regards,
