Tcl_AllowExceptions - allow all exceptions in next script evaluation
Tcl_Interp *interp (in) Interpreter in which script will be
If a script is evaluated at top-level (i.e. no other scripts are pend-
ing evaluation when the script is invoked), and if the script termi-
nates with a completion code other than TCL_OK, TCL_CONTINUE or
TCL_RETURN, then Tcl normally converts this into a TCL_ERROR return
with an appropriate message.
However, if Tcl_AllowExceptions is invoked immediately before calling a
procedure such as Tcl_Eval, then arbitrary completion codes are permit-
ted from the script, and they are returned without modification. This
is useful in cases where the caller can deal with exceptions such as
TCL_BREAK or TCL_CONTINUE in a meaningful way.
