vCont request

[Eli Zaretskii]

Can someone please tell me what is the advantage of using the vCont
request in the remote protocol?

>From reading the sources, I see that remote.c:remote_resume uses an
alternative method via the `c' or `s' packets, but it isn't clear why
vCont is preferred.  From various hints in the manual I vaguely
understand that this involves resuming different threads with
different conditions/signals, but the details are sketchy at best.  In
particular, what GDB user-level commands are affected by availability
of vCont?

I need this information to clarify the relevant manual sections.

TIA
