[lwip-devel] [bug #47092] Tag memory buffers like memp_memory_xxx and ram_heap with a macro so that attributes can be attached to teir definitions

[David Fernandez]

Follow-up Comment #3, bug #47092 (project lwip):

Sorrr fro the late reply, Google decided to put this in the spam folder.

In response to comment #1:

I need to be able to apply the attributes to existing standard pools, that are
considered private... I think what you offer works only for new additional
pools.

As you can see, I'm doing a bit of a trick in memp_extra.h (see the end of the
"original submission"), passing -includememp_extra.h as a gcc option when
compiling lwIP, to achieve that, but lwIP should provide a proper way to do
that.

Similarly for ram_heap.

Not sure what is not clear from my comments. All I'm asking is to have a
mechanism, simila to the macros PACK_STRUCT_BEGIN/END to apply attributes
about sections to things like memp_memory_xxx and ram_heap.
