# ares\_version(3)

Get the version number of the library

## NAME

ares\_version - Get the version number of the library

## SYNOPSIS

```
#include <ares.h>
const char *ares_version(int *version)
```

## DESCRIPTION

The **[ares\_version(3)](/ares_version/3.md)** 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).
