.SH SYNOPSIS

.SH ARGUMENTS
.AS Tcl_ChannelType newClientProcPtr in
.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.
.AP "CONST char" *host in
A string specifying a host name or address for the remote end of the connection.
.AP int myport in
A port number for the client's end of the socket.  If 0, a port number
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.
