[gdal-dev] General Memory/Resource leak fixes(Cleanup calls)

[sanjay boddhu]

Hi Even,
            I'm using Visual studio  with devpartner and below is the part of my app(but reproduces the leaks i have mentioned), its just simply reading from a tif file and creating a another one:

main()
{
.........
.........
GDALAllRegister();
GDALDriver *drv = GetGDALDriverManager()->GetDriverByName("GTiff");
GDALDataset *in_img = (GDALDataset*) GDALOpen(input_file_name.c_str(), GA_ReadOnly);
GDALRasterBand *band = in_img->GetRasterBand(1);
unsigned short *in_buff = new unsigned short[size_x * size_y];
band->RasterIO(GF_Read, 0, 0, size_x, size_y, in_buff, size_x, size_y, GDT_UInt16, 0, 0);
GDALDataset *out_img = drv->Create(output_file_name.c_str(), size_x, size_y, 3, GDT_UInt16, NULL);
band = out_img->GetRasterBand(1);
        band->RasterIO(GF_Write, 0, 0, size_x, size_y, in_buff, size_x, size_y, GDT_UInt16, 0, 0);
        
 GDALClose( out_img );
 GDALClose( in_img );

 delete[] in_buff;

       
VSICleanupFileManager();
GDALDestroyDriverManager();
CPLCleanupTLS();
CPLFinderClean();
CPLFreeConfig();

.....
.....
}

If you want precise help, you should mention the exact version of GDAL you're 
using, and report the exact message you get from your memory leak detector, 
including filenames and line numbers. (If you use Valgrind under Linux, a 
Valgrind trace would help a lot). Your source code would of course help to 
see if it's a memory leak in GDAL or in the way you're using it in your code.

Best regards.
