Description:

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() .

Returns:

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).

Note: Use feof() or ferror() to distinguish an end-of-file condition from an error.
