run ./configure --help to get to see where you can set
the sock file for mysql.
For recent versions of PHP, you can use "localhost:/path/to/mysql.sock"
in your mysql_connect call to tell it where to find the socket.

wx::socket
Wx::Socket(3) User Contributed Perl Documentation Wx::Socket(3)
NAME
Wx::Socket - wxSocket* classes
USAGE
use Wx qw(:socket) ;
use Wx::Event qw(EVT_SOCKET_INPUT EVT_SOCKET_LOST) ;
use Wx::Event qw(EVT_SOCKET_CONNECTION) ;
##########
# CLIENT #
##########
my $sock = Wx::SocketClient->new(wxSOCKET_WAITALL);
EVT_SOCKET_INPUT($parent , $sock , &onInput ) ;
EVT_SOCKET_LOST($parent , $sock , &onClose ) ;
$sock->Connect('localhost',5050) ;
if (! $sock->IsConnected ) { print "ERROR
" ;}
sub onInput {
my ( $sock , $this , $evt ) = @_ ;
my $length = 123;
my $buffer ;
$sock->Read($buffer , 1024 , $length ) ;
}
##########
# SERVER #
##########
my $sock = Wx::SocketServer->new('localhost',5050,wxSOCKET_WAITALL);
EVT_SOCKET_CONNECTION($parent , $sock , &onConnect ) ;
if ( !$sock->Ok ) { print "ERROR
" ;}
sub onConnect {
my ( $sock , $this , $evt ) = @_ ;
my $client = $sock->Accept(0) ;
my ($local_host,$local_port) = $client->GetLocal ;
my ($peer_host,$peer_port) = $client->GetPeer ;
$client->Write("This is a data test!
") ;
... or ...
$client->Write( $data , length($data) ) ;
$client->Close ;
}
METHODS
All the methods work as in wxWidgets (see the documentation).
The functions for reading data (Read, ReadMsg, Peek) take 3 arguments, like the Perl read() function:
## To read the data into the variable
$sock->Read($buffer , 1024) ;
... or ...
## To append data at the given offset:
$sock->Read($buffer , 1024 , $offset ) ;
The write functions (Write, WriteMsg, Unread) can be used with 1 or 2 arguments:
$client->Write("This is a data test!
") ;
$client->Write($data , $length) ;
EVENTS
The events are:
EVT_SOCKET
EVT_SOCKET_ALL
EVT_SOCKET_INPUT
EVT_SOCKET_OUTPUT
EVT_SOCKET_CONNECTION
EVT_SOCKET_LOST
The EVT_SOCKET works as in wxWidgets, the others are wxPerl extensions.
Note that EVT_SOCKET events of wxSocketClient and wxSocketServer work differently than other event types.
First you need to set the event handler:
$sock->SetEventHandler($handler, $id) ;
Then you set what types of event you want to receive:
## this select all.
$sock->SetNotify(wxSOCKET_INPUT_FLAG|wxSOCKET_OUTPUT_FLAG|
wxSOCKET_CONNECTION_FLAG|wxSOCKET_LOST_FLAG) ;
Enable the event notification:
$sock->Notify(1) ;
And only after this use:
## note that $handler must be the same that was used in
## SetEventHandler
EVT_SOCKET($handler, $id , sub{...} )
To make the events easier to use, all the proccess is automatic, and you just use:
EVT_SOCKET_INPUT($handler , $socket , sub{...} )
EVT_SOCKET_OUTPUT($handler , $socket , sub{...} )
EVT_SOCKET_CONNECTION($handler , $socket , sub{...} )
EVT_SOCKET_LOST($handler , $socket , sub{...} )
## This is for the events not used yet by the above:
EVT_SOCKET_ALL($parent , $socket , sub{...} )
** The new way is better to handle more than one socket in the same time too.
Take a look in the demos.
