Tcl_AllowExceptions(3Tcl)Tcl_AllowExceptions(3Tcl)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 terminates 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 permitted
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
