Get the next character from a file
#include <stdio.h> int getc_unlocked( FILE *fp );
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().
The next character from the input stream pointed to by fp, or EOF if an end-of-file or error condition occurs (errno is set).
