"BOOK Tricks of the Java Programming Gurus" has a chapter that illustrates the concept well.
RS: As a simple hint, you do embedding when your C code contains
#include <tcl.h> ... Tcl_Interp *interp = Tcl_CreateInterp(interp): ...
Then you can create new Tcl commands, link static variables from your C program to Tcl variables, but first of all have the power of Tcl at your fingertips ;-).
I thought there was at least one more call - to some sort of locating the encoding files, etc. function - required?
MJ - When embedding a complete Tcl install (e.g. with init.tcl) the following can be used to completely initialize the embedded Tcl interpreter (copied from TIP 66).
Tcl_Interp * interp; /* Initialise the Tcl library thoroughly */ Tcl_FindExecutable( argv[0] ); /* Create the interp, evaluate "init.tcl" for the script level initialisation. */ interp = Tcl_CreateInterp(); if ( Tcl_Init( interp ) != TCL_OK ) { ... Report the error }
