This can be used as a primitive in implementing some forms of a "patch and continue" debugger feature. | |||
Note that this does <i>not</i> resume the debuggee's execution; it merely adjusts the debuggee's state to what it would be if this frame were about to make this call. You must return <code>true</code> from the hook function to resume execution in that state. | Note that this does <i>not</i> resume the debuggee's execution; it merely adjusts the debuggee's state to what it would be if this frame were about to make this call.
