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.
