title: Linux newbie: Linux vs POSIX manual
body: <pre><code>$ apropos mkfifo
  mkfifo (1)           - make FIFOs (named pipes)
  mkfifo (1posix)      - make FIFO special files
  mkfifo (3)           - make a FIFO special file (a named pipe)
  mkfifo (3posix)      - make a FIFO special file
  mkfifoat (3)         - make a FIFO (named pipe) relative to a directory file ...
  </code></pre>
  
  <p>So I have man pages for Linux Programmer’s Manual and POSIX Programmer’s Manual. Which should I prefer and why? (I'm writing a Linux application, no plans to port it AIX, BSD etc)</p>
  
  <p>Thanks.</p>
