Copy a file in a sane way:
#include <fstream> int main() { std::ifstream src("from.ogv", std::ios::binary); std::ofstream dst("to.ogv", std::ios::binary); dst << src.rdbuf(); }
This is so simple and intuitive to read it is worth the extra cost. If we were doing it a lot, better to fall back on OS calls to the file system. I am sure boost
has a copy file method in its filesystem class.
There is a C method for interacting with the file system:
#include <copyfile.h> int copyfile(const char *from, const char *to, copyfile_state_t state, copyfile_flags_t fla
