Welcome reprint, but please keep the author information

in theVSWhen debugging, there are three types of single-step action-by-statement, process-stepping and jumping-out, when doing these three operations,SDMThe call is actually the same callback:

This method is deprecated.        Use the Idebugprocess3::step method instead.         <summary>//Performs a step.  In case there are any thread synchronization or communication between threads, and other threads in the program        Should run when a particular thread is stepping.            </summary> public int Step (IDebugThread2 pThread, Enum_stepkind SK, Enum_stepunit step) {            if (_mixedmode) {return constants.e_notimpl; } var thread = ((Ad7thread) pThread).            Getdebuggedthread (); Switch (SK) {case Enum_stepkind. Step_into:thread. Stepinto ();                Break Case Enum_stepkind. Step_out:thread. StepOut ();                Break Case Enum_stepkind. Step_over:thread. Stepover ();            Break        } return CONSTANTS.S_OK; }

we convert it to gdb the command:

        internal void Sendstepout (long threadId) {            Debugwritecommand ("StepOut");            Execdone ("-exec-return");            var stepcomp = StepComplete;            Pythonthread TRD = _threads[threadid];            if (Stepcomp! = null)            {                Stepcomp (this, new Threadeventargs (TRD));}        }        internal void Sendstepover (long threadId) {            Debugwritecommand ("Stepover");            ExecCommand ("-exec-next");        }        internal void Sendstepinto (long threadId) {            Debugwritecommand ("Stepinto");            ExecCommand ("-exec-step");        }

gdb execute stepout is slightly different from the other two operations when executing stepout when

-exec-return

^done,frame={level= "0", func= "Callee3",

Args=[{name= "Strarg",

value= "0x11940 \" A string Argument.\ ""}],

File= ". /.. /.. /DEVO/GDB/TESTSUITE/GDB.MI/BASICS.C ",

Fullname= "/HOME/FOO/BAR/DEVO/GDB/TESTSUITE/GDB.MI/BASICS.C", line= "18"}

which means it directly outputs the ^done while the other two operations use the *stopped Information:

-exec-step

^running

(GDB)

*stopped,reason= "End-stepping-range", line= ", file=" recursive2.c "

The same thing is that event notifications must be sent at the end of these three operations SDM :

        private void Onstepcomplete (object sender, Threadeventargs e)        {            Send (new Ad7steppingcompleteevent (), AD7STEPPINGCOMPLETEEVENT.IID, _threads[e.thread]);        }

Get!

Now we can VS used in gdb do one step debugging!
