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) system call. On failure an explanation will be printed to stderr, obtained from explain_accept(3), 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) system call.

sock_addr

The sock_addr, exactly as to be passed to the accept(2) system call.

sock_addr_size

The sock_addr_size, exactly as to be passed to the accept(2) system call.

Returns:

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