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 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. AUTHOR
