# explain\_getaddrinfo\_or\_die(3)

network address translation and report errors

## NAME

explain\_getaddrinfo\_or\_die - network address translation and report errors

## SYNOPSIS

\#include \<libexplain/getaddrinfo.h\>

void explain\_getaddrinfo\_or\_die(const char \*node, const char \*service, const struct addrinfo \*hints, struct addrinfo \*\*res);

## DESCRIPTION

The **explain\_getaddrinfo\_or\_die** function is used to call the [*getaddrinfo*(3)](/getaddrinfo/3.md) system call.  On failure, an explanation will be printed to *stderr*, obtained from [*explain\_getaddrinfo*(3)](/explain_getaddrinfo/3.md), and then the process terminates by calling `exit(EXIT_FAILURE)`.

This function is intended to be used in a fashion similar to the following example:

```
explain_getaddrinfo_or_die(node, service, hints, res);
```

- *node*

  The node, exactly as to be passed to the [*getaddrinfo*(3)](/getaddrinfo/3.md) system call.

- *service*

  The service, exactly as to be passed to the [*getaddrinfo*(3)](/getaddrinfo/3.md) system call.

- *hints*

  The hints, exactly as to be passed to the [*getaddrinfo*(3)](/getaddrinfo/3.md) system call.

- *res*

  The res, exactly as to be passed to the [*getaddrinfo*(3)](/getaddrinfo/3.md) system call.

- Returns:

  This function only returns on success. On failure, prints an explanation and exits.

## SEE ALSO
