- .SH NAME
- Tk_RegisterInterp \- make an interpreter accessible with ``send'' command
- .SH SYNOPSIS
- .nf
- \fB#include <tk.h>\fR
- .sp
- int
- \fBTk_RegisterInterp\fR(\fIinterp, name, tkwin\fR)
- .SH ARGUMENTS
- .AS Tk_Window parent
- .AP Tcl_Interp *interp in
- Interpreter to register in display associated with \fItkwin\fR.
- Also used to return errors if registration failed.
- .AP char *name in
- Name under which to register interpreter. Must be unique among
- all registered interpreters for \fItkwin\fR's display. May not
- contain the character ``|''.
- .AP Tk_Window tkwin in
- Token for window. Used only to find a display in which to
- register \fIinterp\fR.

- .SH DESCRIPTION
- .PP
- \fBTk_RegisterInterp\fR is invoked to associate a name (\fIname\fR) with a
- Tcl interpreter (\fIinterp\fR) and record that association in a well-known
- property of a particular display (the one containing \fItkwin\fR).
- After this procedure has been invoked, other interpreters in the
- display will be able to use the \fBsend\fR command to invoke operations
- remotely in \fIinterp\fR. The procedure returns TCL_OK if the
- registration completed successfully and TCL_ERROR if the interpreter
- could not be registered (e.g. because \fIname\fR is already in use).
- In the event of an error, \fIinterp->result\fR is modified to point
- to a message describing the error.
- .PP
- This procedure also adds a \fBsend\fR command to \fIinterp\fR, so
- that commands may be sent from \fIinterp\fR to other interpreters.
- .PP
- The registration persists until the interpreter is deleted or the
- \fBsend\fR command is deleted from \fIinterp\fR, at which
- point \fIinterp\fR is automatically unregistered.
- .PP
- \fBTk_RegisterInterp\fR is called automatically by \fBTk_CreateMainWindow\fR,
- so applications don't normally need to call it explicitly.
