The jsdebugger forum seems to be dead (not used) so I put my question here
instead.

What is wrong with this basic outline?  (some code skipped for brevity)

rt = JS_NewRuntime(0x100000);
cx = JS_NewContext(rt, 0x1000);
global = JS_NewObject(cx, &global_class, NULL, NULL);
JS_InitStandardClasses(cx, global);
....setup function structs here...
JSBool ok= JS_DefineFunctions(cx, global, my_functions);

//Debugger setup part...
JSDContext* pJSDContext = JSD_DebuggerOnForUser(rt, NULL, NULL);
JSD_JSContextInUse(pJSDContext, cx);  //Associate the debugger with the
context we are using.

//These are set from a DebugController wrapper class. this refers to the
class itself.
//The file scope DC... static methods just call back into the class
JS_SetNewScriptHook(pRunTime,      &DCNewScriptHook, this );
JS_SetExecuteHook(pRunTime,    &DCExecuteHook, this);

JSD_SetScriptHook(pJSDContext,     &DCScriptHookProc, this);
JSD_SetThrowHook(pJSDContext,   &DCThrowHook, this);
JSD_SetDebugBreakHook(pJSDContext, &DCDebugBreakHookProc, this );
JSD_SetErrorReporter(pJSDContext,  &DCErrorReporter, this);

ok = JS_EvaluateScript(cx, global, script, strlen(script), filename, lineno,
&rval);
str = JS_ValueToString(cx, rval);
JSD_DebuggerOff(pJSDContext);

I want to call JSD_SetExecutionHook to set a breakpoint.
However it requires a JSDScript* as an argument.

Where do I call JSD_SetExecutionHook from and how do I get a JSDScript* in
the first place?
Do I need to load, compile, and execute instead of using JS_EvaluateScript?

What is the trick here?
Thanks for your help!

So many callbacks...so little time....

Mike
