title: C++ wrapper for posix and linux specific functions
body: <p>Do you know about any good library wrapping posix and linux functions and structures ( eg. sockets or file descriptors ) into C++ classes? For example I'm thinking about a base FileDescriptor class and some inheriting classes ( unix sockets etc ) with methods like write, read or even some syscalls ( sendfile, splice ) - all throwing exceptions instead of setting errno. Or some shared memory class etc.</p>
  
  <p>I can't seem to find anything like that and by now I consider writing it myself, as I often have to write a C++ app for linux and either use C functions ( painful error checking ), or wrap them myself every time.</p>
  
  <p>---EDIT---</p>
  
  <p>Well neither QT nor Boost will compile on the system, we're using - it's a small linux kernel based on 2.4.29 installed on embedded computers.</p>
