Tcl Library Procedures
Tcl_AllowExceptions - allow all exceptions in next script evaluation
Tcl_Interp *interp (in)
Interpreter in which script will be evaluated.
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
This is useful in cases where the caller can deal with exceptions
such as TCL_BREAK or TCL_CONTINUE in a meaningful way.
