    Depends on what you're running asynchronously and for how long.

    You can get very limited functionality through alarm() and a signal handler.
    alarm(2) - Linux manual page
    sigaction(2) - Linux manual page

    But bear in mind, what you can call inside a signal handler is very limited. You couldn't call for example printf.
    signal-safety(7) - Linux manual page


    If it's all I/O that you want to be asynchronous, then perhaps this.
    aio(7) - Linux manual page


    For full blown do whatever you need async, then go for threads.
    pthreads(7) - Linux manual page
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.

    Where will the code be running?

    i.e, Linux, Windows, AVR, PIC, ...
