parameters.
A pointer to the buffer, in which the result is stored, is available in
@code{*@var{result}} after the function call successfully returned. If
an error occurs or if no entry is found, the pointer @code{*@var{result}}
is a null pointer. Success is signalled by a zero return value. If the
function failed the return value is an error number. In addition to the
errors defined for @code{gethostbyname} it can also be @code{ERANGE}.
In this case the call should be repeated with a larger buffer.
Additional error information is not stored in the global variable
@code{h_errno} but instead in the object pointed to by @var{h_errnop}.

buffer passed as the @var{buf} parameter can be freed only once the caller
has finished with the result hostent struct, or has copied it including all
