# explain\_socket\_or\_die(3)

create an endpoint and report errors

## NAME

explain\_socket\_or\_die - create an endpoint and report errors

## SYNOPSIS

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

void explain\_socket\_or\_die(int domain, int type, int protocol);

## DESCRIPTION

The **explain\_socket\_or\_die** function is used to call the [*socket*(2)](/socket/2.md) system call.  On failure an explanation will be printed to *stderr*, obtained from [*explain\_socket*(3)](/explain_socket/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_socket_or_die(domain, type, protocol);
```

- *domain*

  The domain, exactly as to be passed to the [*socket*(2)](/socket/2.md) system call.

- *type*

  The type, exactly as to be passed to the [*socket*(2)](/socket/2.md) system call.

- *protocol*

  The protocol, exactly as to be passed to the [*socket*(2)](/socket/2.md) system call.

- Returns:

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

## SEE ALSO

- [*socket*(2)](/socket/2.md)

  create an endpoint for communication

- [*explain\_socket*(3)](/explain_socket/3.md)

  explain [*socket*(2)](/socket/2.md) errors

- [*exit*(2)](/exit/2.md)

  terminate the calling process
