NAME

explain_connect_or_die - initiate a connection on a socket and report errors

SYNOPSIS

#include <libexplain/connect.h>
void explain_connect_or_die(int fildes, const struct sockaddr *serv_addr, int serv_addr_size);

DESCRIPTION

The explain_connect_or_die function is used to call the connect(2) system call. On failure an explanation will be printed to stderr, obtained from explain_connect(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:

explain_connect_or_die(fildes, serv_addr, serv_addr_size);

fildes

The fildes, exactly as to be passed to the connect(2) system call.

serv_addr

The serv_addr, exactly as to be passed to the connect(2) system call.

serv_addr_size

The serv_addr_size, exactly as to be passed to the connect(2) system call.

Returns:

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