Every RTOS has its own proprietary API, but some also support the POSIX standards. Here's a look at the parts of POSIX that apply to real-time systems. In today's computing systems, it is becoming ...

I'm designing a library using POSIX that needs to sit on a few FDs and wake up when data is available. Just like select() and poll() have done for me for years. But now I gotta be ...
