Decompression of files C+

A function in C+ to decompress a file, and place the result in a buffer. Compress type can be any file compression type with good ratio, but using a standard compression ( RAR, ZIP ) format will have first priority - else we have to also write a compression function. Buffer to place the result shall be created dynamicaly with dynamic size. Buffer size "BufferSize" returned on success. If an "embedded" function like this already exists as standard, this solution will have priority. No folders, only one file to decompress. Function could look like this, and must be a stand-alone function, no DLL´s: long DecompressFile( char * Buffer, const String FileName) { long BufferSize; //-------- Decompress file ---- //-------- If no errors ------- return BufferSize; //--------- If errors --------- return 0; } ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law.
