# explain\_accept\_or\_die(3)

accept a connection on a socket and report errors

## NAME

explain\_accept\_or\_die - accept a connection on a socket and report errors

## SYNOPSIS

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

int explain\_accept\_or\_die(int fildes, struct sockaddr \*sock\_addr, socklen\_t \*sock\_addr\_size);

## DESCRIPTION

The **explain\_accept\_or\_die** function is used to call the [*accept*(2)](/accept/2.md) system call.  On failure an explanation will be printed to *stderr*, obtained from [*explain\_accept*(3)](/explain_accept/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:

```
int fd = explain_accept_or_die(fildes, sock_addr, sock_addr_size);
```

- *fildes*

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

- *sock\_addr*

  The sock\_addr, exactly as to be passed to the [*accept*(2)](/accept/2.md) system call.

- *sock\_addr\_size*

  The sock\_addr\_size, exactly as to be passed to the [*accept*(2)](/accept/2.md) system call.

- Returns:

  This function only returns on success, see [*accept*(2)](/accept/2.md) for more information.  On failure, prints an explanation and exits.

## SEE ALSO

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

- [*explain\_accept*(3)](/explain_accept/3.md)
