NAME¶

explain_getaddrinfo_or_die - network address translation and report errors

SYNOPSIS¶

#include <libexplain/getaddrinfo.h>

void explain_getaddrinfo_or_die(const char *node, const char *service, const struct addrinfo *hints, struct addrinfo **res);

DESCRIPTION¶

The explain_getaddrinfo_or_die function is used to call the getaddrinfo(3) system call. On failure, an explanation will be printed to stderr, obtained from explain_getaddrinfo(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_getaddrinfo_or_die(node, service, hints, res);

node

The node, exactly as to be passed to the getaddrinfo(3) system call.

service

The service, exactly as to be passed to the getaddrinfo(3) system call.

hints

The hints, exactly as to be passed to the getaddrinfo(3) system call.

res

The res, exactly as to be passed to the getaddrinfo(3) system call.

Returns:

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