Hi,
I'd like to have your expertise on writing in random mode - after setting the current pointer with fseek - into an existing binary file. I'm getting somehow confused with a bunch of options for fopen_s, including an "R" (for random), and a "c" to force "hard flushing" into the disk (bypassing the system's buffers), that I read about for the first time. What would be the right function to write - so that to avoid writing byte by byte?
Thanks!
