.\" The definitions below are for supplemental macros used in Sprite
.\" manual entries.
.\"
.\" .HS name section [date [version]]
.\"	Replacement for .TH in other man pages.  See below for valid
.\"	section names.
.\"
.\" .AP type name in/out [indent]
.\"	Start paragraph describing an argument to a library procedure.
.\"	type is type of argument (int, etc.), in/out is either "in", "out",
.\"	or "in/out" to describe whether procedure reads or modifies arg,
.\"	and indent is equivalent to second arg of .IP (shouldn't ever be
.\"	needed;  use .AS below instead)
.\"
.\" .AS [type [name]]
.\"	Give maximum sizes of arguments for setting tab stops.  Type and
.\"	name are examples of largest possible arguments that will be passed
.\"	to .AP later.  If args are omitted, default tab stops are used.
.\"
.\" .BS
.\"	Start box enclosure.  From here until next .BE, everything will be
.\"	enclosed in one large box.
.\"
.\" .BE
.\"	End of box enclosure.
.\"
.\" .VS
.\"	Begin vertical sidebar, for use in marking newly-changed parts
.\"	of man pages.
.\"
.\" .VE
.\"	End of vertical sidebar.
.\"
.\" .DS
.\"	Begin an indented unfilled display.
.\"
.\" .DE
.\"	End of indented unfilled display.

.SH NAME
DP_RPC - C access to Tcl-DP remote procedure call commands
.SH SYNOPSIS
.nf
.sp
\fB#include "network.h"\fR
.sp
int \fBTdp_RPC (\fIinterp, filePtr, command, events, timeout, timeoutReturn\fB)\fR
.SH ARGUMENTS
.AS Tcl_Interp *command
.AP Tcl_Interp *interp in
Tcl interpreter, mainly for error messages.
.AP OpenFile *filePtr in
Represents an RPC connection to a remote Tcl/Tk process.
.AP char *command in
Tcl/Tk command to be evaluated in the remote Tcl/Tk interpreter.
.AP int events in
Passed to \fBTk_DoOneEvent\fR while waiting for RPC return value.
.AP int timeout in
Integer milliseconds.
.AP char *timeoutReturn in
Tcl command to eval in case of timeout.
.BE
.SH DESCRIPTION
.PP

The above routines give C access to the Tcl-DP remote procedure
call commands (\fBdp_RPC\fR and \fBdp_RDO\fR).  

If the \fIevents\fR argument is less than 0, then no events are
handled while waiting for an RPC return value on the given RPC
connection.  If the \fIevents\fR argument is not less than 0,
then the \fIevents\fR argument is the same type of argument as
passed to \fBTk_DoOneEvent\fR and allows one to flag for the
event types which will be handled while waiting for an RPC return
value.  This \fIevents\fR argument, if not less than 0, is
automatically or'ed with TK_FILE_EVENTS flag so that file events
are always handled.

If the \fItimeout\fR argument is zero or less than zero, timeout
will not be checked.
