[gdal-dev] Error in GDALWarp to NWT_GRD

[jramm]

I added the following to the end of the Create method in
frmts/northwood/grddataset.cpp:


    vsi_l_offset nFileSize = 1024 + nXSize * nYSize * 2;
    if (VSIFTruncateL(poDS->fp, nFileSize) != 0) {
		CPLError(CE_Failure, CPLE_FileIO,
				"Failed to allocate space for GRD file");
		delete poDS;
		return NULL;
    }
    poDS->FlushCache(); // Write the header to disk.

Unfortunately still receiving the error. I wonder if it would be better if I
explicitly write the zeros with VSIFWriteL?
