[9fans] Question About 9p headers...

[maynard]

Greetings,

[preamble] I'm at the low end of a re-leaning curve of Plan 9 so be
nice :)

I'm currently working on a 9p stub for an embedded controler exporting
a (not yet fully defined) local namespace. The problem (or confusion)
I am having is;
not knowing fully the header files that will be necessary to write the
stub.
Lack of intrinsics knowledge, coupled with a bastardized (not fully
ansi/posix)
compiler is not helping (i.e. enum, pragma, etc. !supported). Other
aspects are covered like tcp/ip stack, loader libs are supplied and
not an issue.  Finding like code examples are a little scarce (as far
as i can tell).  If anyone can
->me to some stub examples, or let me know the headers that would be
required...sigh I'm already greatful :). In case you're wondering, yes
I'm stuck using this compiler since is contains the controller bios,
loader,etc. no time to develop that kinda thing.  I have considered
Limbo/Styx but... /shrug not would prefer to do it using just 9p
proper.  (Plus not sure if it is 9pv4 ready)

Thanks in advace
Maynard

The 9p(2) manual page suggests some nice examples. Although
they're implemented using libraries that make it easier, the
code in the libraries is easy to read too. IMHO, that's a
good place to start.

If you are doing something embedded, you may not be
able to fit all the extra checks that lib9p does.
Have a look at /sys/src/cmd/ramfs.c, which is a good
small standalone functioning 9P server.

Thanks much guys been spending all weekend unwinding u9fs and ramfs
:)now as I head to bed I read your replies...haha..well at least i was
on the money.  It's getting kinda dicey tyring to unwind them however
since their (both) written with an underlying OS, but still working on
it. I guess the part I'm brain farting over is the mechanism to
statically build a namespace without. It's not obvious, but you know
what they say..'can't see the tree'.  Thanks again for the direction,
chugging away
