NIH at work. In C and C++ the standard fixed bit length data types are available
in #include <stdint.h> as uint8_t, uint16_t, uint32_t, uint64_t & co.

BTW, the definition of UINT32 as "unsigned int" is technically incorrect, on 16-bit machines
"int" is 16-bit wide and on some 64-bit machines "int" is 64-bit wide.

K.O.
