Integral Datatypes
..................
The integral datatypes used in the system calls are 'int', 'unsigned
int', 'long', 'unsigned long', 'mode_t', and 'time_t'.
'int', 'unsigned int', 'mode_t' and 'time_t' are implemented as 32
bit values in this protocol.
'long' and 'unsigned long' are implemented as 64 bit types.
Limits, for corresponding MIN and MAX values (similar to
those in 'limits.h') to allow range checking on host and target.
'time_t' datatypes are defined as seconds since the Epoch.
All integral datatypes transferred as part of a memory read or write
of a structured datatype e.g. a 'struct stat' have to be given in big
endian byte order.
