ZLib

I'm working on an application which transfers huge data from server (Web API) to client (JavaScript) which takes some time over the network. So we decided to go with compression in server and decompression in client. I have used Zlib for .NET to compress my file. Below is the code which I have...

How i can get the crc32 of a ULONGLONG using zlib? What I have tried: char * token; char * getcrc(ULONGLONG var) { unsigned long crc = crc32(0, (const Bytef*)&var, sizeof(__int64)); token = new char[1000]; sprintf(token, "CRC: %u", crc); return token; }

It should work the way you are doing it. All you have to do is including zlib.h and linking your application with the zlib library. To be correct you should use the same type for the length: sizeof(ULONGLONG).

Zlib compress / decompress implementation using .NET 4.5.1, with no external DLLs
