"Does anyone know how strings are stored in GNAT,
and thus how they can be sent from C.

I think a pointer is first sent to the string and then
a pointer to a structure containing first and last pointers
but I am not absolutely sure this is correct.

Any help would be much appreciated,"

You should not write C at this level. Instead to pass strings across
the Ada-C interface, use the protable routines defined in and under
Interfaces.C.
