Function Documentation

void explain_buffer_errcode_getaddrinfo	(	explain_string_buffer_t *	sb,
		int	errcode,
		const char *	node,
		const char *	service,
		const struct addrinfo *	hints,
		struct addrinfo **	res
	)

The explain_buffer_errcode_getaddrinfo function is used to obtain an explanation of an error returned by the getaddrinfo(3) system call. The least the message will contain is the value of gai_strerror(errcode), but usually it will do much better, and indicate the underlying cause in more detail.

Parameters:

sb	The string buffer to print the message into. If a safe buffer is specified, this function is thread safe.
errcode	The error value to be decoded, as returned by the getaddrinfo system call.
node	The original node, exactly as passed to the getaddrinfo(3) system call.
service	The original service, exactly as passed to the getaddrinfo(3) system call.
hints	The original hints, exactly as passed to the getaddrinfo(3) system call.
res	The original res, exactly as passed to the getaddrinfo(3) system call.
