{
  This unit contains all access functions to libc (unix like OS like
  Linux, Mac OS X, BSD), which are needed by the IDE, but are not provided
  by FPC units SysUtils, Unix and BaseUnix.

  Before adding stuff here always check if fpc units Unix or BaseUnix already
  contains corresponding functions.
  Always use types from the ctypes unit.
