Use the -l c option to qcc to link against this library. This library is usually included automatically.
The putc_unlocked() function is a thread-unsafe version of putc() . You can use it safely only when the invoking thread has locked stream using flockfile() (or ftrylockfile() ) and funlockfile() .
The character written, cast as (int)(unsigned char), or EOF if an error occurred ( errno is set).
