ARES_VERSION(3) 								  ARES_VERSION(3)

NAME
       ares_version - Get the version number of the library

SYNOPSIS
       #include <ares.h>

       const char *ares_version(int *version)

DESCRIPTION
       The  ares_version function gets the library version as a string and optionally as an inte-
       ger stored in the version, 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).

NOTES
       This function is not compatible with ares.
