libc
Use the -l c option to qcc to link against this library. This library is usually included automatically.
The getc_unlocked() function is a thread-unsafe version of getc(). You can use it safely only when the invoking thread has locked fp using flockfile() (or ftrylockfile()) and funlockfile().
