  .TH ARES_VERSION 3 "29 January 2004"
  .SH NAME
  ares_version \- Get the version number of the library
  .SH SYNOPSIS
  .nf
  #include <ares.h>
  
  const char *ares_version(int *\fIversion\fP)
  .fi
  .SH DESCRIPTION
  The \fBares_version(3)\fP function gets the library version as a string and
  optionally as an integer stored in the \fIversion\fP argument. If you pass a
  NULL, no integer is attempted to be returned.
  
  The integer is built up as 24bit number, with 8 separate bits used for major
  number, minor number and patch number. This makes a version string such as
  1.2.3 will be returned as the hexadecimal number 0x010203 (decimal 66051).
