Re: [RFA] More wrappers in varobj


Sorry for the delay. I got a little caught up in debugging some
other stuff...

Is this better?

Slightly off-topic: We are going to be calling externally visible
functions something like "gdb_FOO", right? Example: gdb_breakpoint and
gdb_breakpoint_query. How are we going to name internal functions? Leading
"_" or something?

I ask because I don't really want to have this patch introduce
internal variations of gdb functions into the "libgdb" namespace.
