Unhandled exception at 0x77f966bc in SDLOGL_Engine.exe: 0xC0000022: } A process has requested access to an object, but has not been granted those access rights. this is the error that occurs even after i have commented out the entire main() function. like: int main(int argc, char *argv[]) { /* code here */ } and i am posetive that the error occures AFTER the end of main() any ideas on what i can look for *the thing i have to fix* ? and what does the error meen ?

It could be in a destructor of a local object in main or in a destructor of a global object or in a function registerd with atexit.

That tended to happen to me when I had linking problems; ie linking with the wrong CRT, or linking with some strange parameters.

Strangely, only a re-build of the project file (delete the .VCPROJ or the .MAK and make it from scratch again) seemed to get rid of it, so I never found out what the error was. And I hadn''t modified the linker options, anyways...

did some more width the debuger and the error is located here:

and im posetive that its after the last instruction in my main() loop


int __cdecl fclose (
        FILE *stream
        )
{
        int result = EOF;

        _ASSERTE(stream != NULL);

        /* If stream is a string, simply clear flag and return EOF */
        if (stream->_flag & _IOSTRG)
                stream->_flag = 0;  /* IS THIS REALLY NEEDED ??? */

        /* Stream is a real file. */
        else { 
                _lock_str(stream); // < - HERE IS THE ERROR !
                __try {
                        result = _fclose_lk(stream);
                }
                __finally {
                        _unlock_str(stream);
                }
        }

        return(result);
}

Also i found out that if i comment out the ONLY function that i have that uses the fclose() i dont get the crash i cant understand why tho ... so im posting it here :


uint GTextureHandler::LoadTexture(const char *pszFile, int iTex )
{
	
	t_Texture* tex = PopTexture();

	FILE *fp;
	BITMAPFILEHEADER	bitmapFileHeader;
	BITMAPINFOHEADER	bitmapInfoHeader;
	uint				imageIdx = 0;
	uchar				tmpRGB;

	fp = fopen(pszFile, "rb");
	if (fp == NULL)
	{
		MsgBoxE("Missing texture file. \n Aborting " );
		GQuit();
		return( NULL );
	}

	fread(&bitmapFileHeader, sizeof(BITMAPFILEHEADER), 1, fp);
	
	if (bitmapFileHeader.bfType != BMP_IMAGE_ID)
	{
		MsgBoxE("Wrong bmp type" );
		fclose(fp);
		return( NULL );
	}

	fread( &bitmapInfoHeader, sizeof(BITMAPINFOHEADER), 1, fp );
	fseek( fp, bitmapFileHeader.bfOffBits, SEEK_SET );


	tex->pData = (unsigned char*)malloc( bitmapInfoHeader.biSizeImage );
	if( tex->pData == NULL )
	{
		MsgBoxE("Error allocatin memory for image" );
		free( tex->pData );
		fclose(fp);
		return( NULL );
	}

	
	fread( tex->pData, 1, bitmapInfoHeader.biSizeImage, fp);
	if( tex->pData == NULL)
	{
		MsgBoxE("ERROR: Cant read the img correctly" );
		fclose( fp );
		return( NULL );
	}

	for (imageIdx = 0; imageIdx < bitmapInfoHeader.biSizeImage; imageIdx+=3)
	{
		tmpRGB = tex->pData[imageIdx];
		tex->pData[imageIdx] = tex->pData[imageIdx + 2];
		tex->pData[imageIdx + 2] = tmpRGB;
	}

	fclose( fp );

	tex->bUsed = true;
	glGenTextures(1, &tex->iTex);
	glBindTexture(GL_TEXTURE_2D,tex->iTex);

	glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_NEAREST);
	glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_NEAREST);

	glTexImage2D(GL_TEXTURE_2D, 0, GL_RGB, bitmapInfoHeader.biWidth,
		bitmapInfoHeader.biHeight, 0, GL_RGB, GL_UNSIGNED_BYTE, tex->pData);

	g_Textures[iTex] = tex->iTex;
/**/
	return( iTex );
}
