<p class="MsoNormal" style="margin-bottom:0.0001pt"><span style="font-size:12pt;font-family:Arial,sans-serif">Since the communication
is in between Erlang and C nodes, you don't have to worry about
marshaling/un-marshaling the data at the Erlang node side. You can send and
receive 'messages' in the 'record tuple' format. But, at the C node side,
you have the work. You will have to hand code marshaling/un-marshaling routines
to populate the Erlang ‘records’ or to populate the C structures.</span></p>

<p class="MsoNormal" style="margin-bottom:0.0001pt"><span style="font-size:12pt;font-family:Arial,sans-serif">It very simple to edit C
structures into Erlang records. I don’t think you will have to invent an interpreter
for that. May be, you want to have a utility to generate marshaling/un-marshaling
routines in C, from your C structures.</span></p>

<p class="MsoNormal" style="margin-bottom:0.0001pt"><span style="font-size:12pt;font-family:Arial,sans-serif">If you are familiar with
C preprocessor techniques, you can simply write a reusable module to generate
marshaling/un-marshaling routines, and of course relevant Erlang records, with
the help of a ‘definition file’.</span></p>
