Tcl_AllowExceptions(3) Tcl Library Procedures Tcl_AllowExceptions(3)
__________________________________________________________________________________________________________________________________________________
NAME
Tcl_AllowExceptions - allow all exceptions in next script evaluation
SYNOPSIS
#include <tcl.h>
Tcl_AllowExceptions(interp)
ARGUMENTS
Tcl_Interp *interp (in) Interpreter in which script will be evaluated.
_________________________________________________________________
DESCRIPTION
If a script is evaluated at top-level (i.e. no other scripts are pending evaluation when the script is invoked), and if the script termi-
nates with a completion code other than TCL_OK, TCL_ERROR or TCL_RETURN, then Tcl normally converts this into a TCL_ERROR return with an
appropriate message. The particular script evaluation procedures of Tcl that act in the manner are Tcl_EvalObjEx, Tcl_EvalObjv, Tcl_Eval,
Tcl_EvalEx, Tcl_GlobalEval, Tcl_GlobalEvalObj, Tcl_VarEval and Tcl_VarEvalVA.
However, if Tcl_AllowExceptions is invoked immediately before calling one of those a procedures, then arbitrary completion codes are per-
mitted 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.
KEYWORDS
continue, break, exception, interpreter
