Perhaps the simplest solution uses one of my favorite little-known functions, strcspn():
buffer[strcspn(buffer, "\n")] = 0;

buffer[strcspn(buffer, "\r\n")] = 0; // works for LF, CR, CRLF, LFCR, ...

Why are only a few video games written in Java? [closed]
...conds while it scans all the allocated memory to see what can be freed. I know Java tends to choke quite a bit in GC'ing when it's close to running out of memory (and for some games out there, it will).
You're also a bit more restricted in what you can do: you can't fully exploit the hardware due t...

How to filter (key, value) with ng-repeat in AngularJs?

{
// Key wasn't in dictionary; "value" is now 0
}
