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<vUnzip*> 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<<e.what()<<endl; } unZipV.push_back(new vUnzip(data,xyz)); totLen+=xyz; if(xyz!=CHUNK) break; } *outBuff=new char[totLen]; int g=0; for(int k=0;k<unZipV.size();++k) { memcpy((*outBuff)+g,unZipV[k]->ptr,unZipV[k]->len); g+=unZipV[k]->len; delete unZipV[k]; } *OutLen=totLen; return true; } ______________________________________ Scanned and protected by Email scanner
