ARES_VERSION(3) 			       Library Functions Manual 			      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 integer stored in the ver-
       sion, 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.
