Fopen Read And Write
Closed 6 years ago.What is a good approach to read the whole file content in a buffer for C?While in plain C I could use fopen, fseek, fread function combination and read the whole file to a buffer, is it still a good idea to use the same for C? Update windows xp sp3 offline 2013 gmc truck. If yes, then how could I use RAII approach while opening, allocating memory for buffer, reading and reading file content to buffer.Should I create some wrapper class for the buffer, which deallocates memory (allocated for buffer) in it's destructor, and the same wrapper for file handling?
