Eli, the only C coding standard I was ever confronted with
is GDB coding standards.
And this is probably one of the first rules
that I understood.
I find this rule quite useful, as it allows
easy tracking of function implementation.

I agree with the principle, but
it is not always possible:
What should we do with this:
$ grep -n -C 3 "^[a-z][a-z0-9_]*[[:space:]]*(.*)" *.h
linux-nat.h-147-/* Create a generic GNU/Linux target using traditional
linux-nat.h-148- ptrace register access. */
linux-nat.h-149-struct target_ops *
linux-nat.h:150:linux_trad_target (CORE_ADDR (*register_u_offset)(struct
gdbarch *, int, int));
linux-nat.h-151-
linux-nat.h-152-/* Register the customized GNU/Linux target. This should be
used
linux-nat.h-153- instead of calling add_target directly. */
OK, I must admit that I cheated, because that did not even appear in the
ARI list,
while it should.
It should be in the list because it is one of the
functions declarations that are in first column,
it does not appear because I oversimplified the rule
using
/^[a-z][a-z0-9_]*[[:space:]]*\((|[^*][^()]*)\)[[:space:]]*[^ \t]+/
awk pattern to avoid getting all function variables.
If someone can suggest a more complete pattern that would also
grab the above without matching
int (*test_var_function (int, int));
I would be grateful.
