explain_connect_or_die - initiate a connection on a socket and report errors

#include <libexplain/connect.h>

void explain_connect_or_die(int fildes, const struct sockaddr *serv_addr, int serv_addr_size);

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);
The fildes, exactly as to be passed to the connect(2) system call.
The serv_addr, exactly as to be passed to the connect(2) system call.
The serv_addr_size, exactly as to be passed to the connect(2) system call.
This function only returns on success. On failure, prints an explanation and exits.

connect(2)
initiate a connection on a socket
explain_connect(3)
explain connect(2) errors
exit(2)
terminate the calling process
