[Boost-users] boost::iostream exception

6 Oct 2008

      Hi,

I am trying to decompress a file using boost::iostreams (1.35.0) library
built with zlib-1.2.3 . I am able to decompress the file with other
utilities but this program throws me an exception saying "gzip error". I
am able to uncompress other gzipped files. What could be the reason for
the exception? Any help is very much appreciated. 

Thanks
 Lloyd

The decompress function is also added here
==========================================

bool ParseHttp::Decompress(const char* inBuff, int inLen,char** outBuff,
int* OutLen,int type)
{
	enum
	{
		CHUNK=4096
	};
	if(inBuff==NULL)
		return false;
	filtering_streambuf<input> in;
	switch(type)
	{
		case GZIP:
			in.push(gzip_decompressor());
		break;
		case ZLIB:
			in.push(zlib_decompressor());
			break;
	}

	in.push(boost::make_iterator_range((const char*)inBuff,(const
char*)inBuff+inLen));
	vector unZipV;
	int totLen=0;
	while(1)
	{
		char* data=new char[CHUNK];
		int xyz=0;
		try
		{
		 xyz=boost::iostreams::read(in,data,CHUNK);
		}
		catch(exception& e)
		{
			if(debug)
				cout<ptr,unZipV[k]->len);
		g+=unZipV[k]->len;
		delete unZipV[k];
	}
	*OutLen=totLen;
	return true;
}
