Dear GDB experts,
I have a request, in some scene, I want to "set scheduler-locking on", then "next", then "scheduler-locking off",
Can I combine the three commands into one?
Thanks,
-Riyue

In your .gdbinit, something like:
define schedlock-next
set scheduler-locking on
next
set scheduler-locking off
end
and then the newly defined schedlock-next command should do what you want.
See e.g. https://sourceware.org/gdb/current/onlinedocs/gdb/Sequences.html#Sequences
for more details.
You can also extend GDB using python or guile.

Not the original question, but why not use "set scheduler-locking step"?
