socket::getaddrinfo::strict
Socket::GetAddrInfo::Strict(3pm) User Contributed Perl Documentation Socket::GetAddrInfo::Strict(3pm)
NAME
"Socket::GetAddrInfo::Strict" - Provide Socket::GetAddrInfo functions which throw exceptions
SYNOPSIS
use Socket qw( SOCK_STREAM );
use Socket::GetAddrInfo::Strict qw( getaddrinfo getnameinfo );
use IO::Socket;
my $sock;
my %hints = ( socktype => SOCK_STREAM );
my @res = getaddrinfo( "www.google.com", "www", \%hints );
while( my $ai = shift @res ) {
$sock = IO::Socket->new();
$sock->socket( $ai->{family}, $ai->{socktype}, $ai->{protocol} ) or
undef $sock, next;
$sock->connect( $ai->{addr} ) or undef $sock, next;
last;
}
if( $sock ) {
my ( $host, $service ) = getnameinfo( $sock->peername );
print "Connected to $host:$service
";
}
DESCRIPTION
Socket::GetAddrInfo provides the functions of "getaddrinfo" and "getnameinfo", which return lists whose first element is error value, or
false indicating no error occured.
This module wraps the functions provided by "Socket::GetAddrInfo" to check this error value, and throw an exception (using "die") if an
error occured. If not, then the remaining values are returned as normal. This can simplify the logic of a program which otherwise simply
throws its own exception on failure anyway.
FUNCTIONS
@res = getaddrinfo( $host, $service, $hints )
After a successful lookup, returns the list of address structures, as documented in Socket::GetAddrInfo. If the lookup fails, an exception
containing the string form of the error is thrown instead.
( $host, $service ) = getnameinfo( $addr, $flags, $xflags )
After a successful lookup, returns the host and service name, as documented in Socket::GetAddrInfo. If the lookup fails, an exception
containing the string form of the error is thrown instead.
