.SH NAME
Tcl_OpenTcpClient, Tcl_MakeTcpClientChannel, Tcl_OpenTcpServer \- procedures to open channels using TCP sockets
.SH SYNOPSIS
.nf
\fB#include <tcl.h> \fR
.sp
Tcl_Channel
\fBTcl_OpenTcpClient\fR(\fIinterp, port, host, myaddr, myport, async\fR)
.sp
Tcl_Channel
\fBTcl_MakeTcpClientChannel\fR(\fIsock\fR)
.sp
Tcl_Channel
\fBTcl_OpenTcpServer\fR(\fIinterp, port, myaddr, proc, clientData\fR)
.sp



.SH ARGUMENTS
.AS Tcl_TcpAcceptProc clientData
.AP Tcl_Interp *interp in
Tcl interpreter to use for error reporting.  If non-NULL and an
error occurs, an error message is left in the interpreter's result.
.AP int port in
A port number to connect to as a client or to listen on as a server.
................................................................................
is allocated at random.
.AP "const char" *myaddr in
A string specifying the host name or address for network interface to use
for the local end of the connection.  If NULL, a default interface is
chosen.
.AP int async in
If nonzero, the client socket is connected asynchronously to the server.



.AP ClientData sock in
Platform-specific handle for client TCP socket.
.AP Tcl_TcpAcceptProc *proc in
Pointer to a procedure to invoke each time a new connection is
accepted via the socket.
.AP ClientData clientData in
Arbitrary one-word value to pass to \fIproc\fR.
................................................................................
a remote client is pending.
.PP
The newly created channel is not registered in the supplied interpreter; to
register it, use \fBTcl_RegisterChannel\fR.
If one of the standard channels, \fBstdin\fR, \fBstdout\fR or \fBstderr\fR was
previously closed, the act of creating the new channel also assigns it as a
replacement for the standard channel.





.SH "PLATFORM ISSUES"
.PP
On Unix platforms, the socket handle is a Unix file descriptor as
returned by the \fBsocket\fR system call.  On the Windows platform, the
socket handle is a \fBSOCKET\fR as defined in the WinSock API.
.SH "SEE ALSO"
Tcl_OpenFileChannel(3), Tcl_RegisterChannel(3), vwait(n)
.SH KEYWORDS
channel, client, server, socket, TCP

If nonzero, the client socket is connected asynchronously to the server.
.AP "unsigned int" flags in
ORed combination of \fBTCL_TCPSERVER\fR flags that specify additional 
informations about the socket being created.
.AP ClientData sock in
Platform-specific handle for client TCP socket.
.AP Tcl_TcpAcceptProc *proc in
Pointer to a procedure to invoke each time a new connection is
accepted via the socket.

.SS TCL_OPENTCPSERVEREX
.PP
\fBTcl_OpenTcpServerEx\fR behaviour is identical to \fBTcl_OpenTcpServer\fR but
gives more flexibility to the user by providing a mean to further customize some
aspects of the socket via the \fIflags\fR parameter.
.SH "PLATFORM ISSUES"
.PP
On Unix platforms, the socket handle is a Unix file descriptor as
returned by the \fBsocket\fR system call.  On the Windows platform, the

server-side network interface to use for the connection.  This option
may be useful if the server machine has multiple network interfaces.
If the option is omitted then the server socket is bound to the
wildcard address so that it can accept connections from any
interface. If \fIaddr\fR is a domain name that resolves to multiple IP
addresses that are available on the local machine, the socket will
listen on all of them.










.PP
Server channels cannot be used for input or output; their sole use is to
accept new client connections. The channels created for each incoming
client connection are opened for input and output. Closing the server
channel shuts down the server so that no new connections will be
accepted;  however, existing connections will be unaffected.

.
Tells the kernel whether to reuse the local address if there's no active socket
listening on it. This is the default on Windows.
.TP
\fB\-reuseport\fI boolean\fR
.
Tells the kernel whether to allow the binding of multiple sockets to the same
socket address. This is the default on Windows.
