Re: [zenith007] Communication between perl script and C programme through sockets
[In reply to]
I need a perl script , which is able to communicate with the C programme on the same local machine through socket programming.
This is one which I have written , but I dont know what causing the problem , the script is unalbe get data
I've tried the code in Perl Cookbook, and many modifications. Here's my socket programme
our $server = IO::Socket::UNIX->new(LocalAddr => "/tmp/mysock",
Type => SOCK_DGRAM,
Listen => 5)
or die $!;
while (my $client = $server->accept())
while (defined (my $buf = <$client>))
When I run it, the ->new() call appears to work. No error codes and the debugger reports that $server is a socket. The /tmp/mysock file doesn't get created, though. Then the while($client = ... ) just falls through. It doesn't wait for the socket to say anything, it just skips to the close() statement and exits.
I've done this with INET sockets a number of times with no problems, but this is the first time I've tried UNIX sockets. If anyone has any ideas, I'd appreciate hearing about them. Thanks Russ Jones
