Re: Debug API single-step mode on multi-thread

Tech-Archive recommends: Fix windows errors by optimizing your registry

In addition to what Tim has already said...

How can I really make a single-step mode:

* step for each thread <----------------------+
|

It is not possible at all to single-step each thread in the process,
because some threads might not be able to execute at all
(e.g. they can be waiting for an unavailable synchronization object,
sleeping, waiting for I/O, suspended from another process,
and so on).

The closest thing you can get is to single-step one thread at a time
(e.g. let the user decide which one) or expect "Step" command
to single-step only those threads that can run (e.g. wait for a predefined
timeout after "Step" command has been issued) and break into
your debugger after that.
