If I've got a detached thread running some C code, how might I go about
executing a Tcl procedure. Ns_TclEval looks like what I'm looking for, but
it needs a server connection (as far as I can tell from the documentation).
If anyone has done this before, or could give me some pointers/examples it'd
be much appreciated.
You could use Tcl_Eval. If you have a detached thread, then you have a Tcl
interpreter (the one calling the C). You could pass that interp pointer to
Tcl_Eval as shown below.
NOTE: completely untested code (that has no error checking):
MyTclCmd(ClientData unused, Tcl_Interp * interp, int argc, char **argv)
{
Tcl_DString tclscript;
/* assuming in this example that argv[1] is the tcl script */
Tcl_DStringInit(&tclscript);
Tcl_DStringAppend(&tclscript, argv[1], strlen(argv[1]));
if (Tcl_Eval(interp, tclscript.string) != TCL_OK) {
/* handle the error */
Ns_TclLogError(interp);
} else {
/* handle result, if wanted, which is in interp->result */
...
}
Tcl_DStringFree(&tclscript);
}
