To share with your C code, this is normally sufficient:

pragma Convention(C, FP_SHARED_BUF_TYPE);

with no need for the representation clause.
GNAT should then give a compatable layout.

In addition, I presume: "POSIX.Mutexes.Descriptor_Of (CMN_SHM.LOCK_MISSION_VARS)"
is needing the address of the parameter - so shouldn't that component of the
record be declared as aliased?
