Typedef Documentation

nsize_t

typedef uint_bytes_t<sizeof(unsigned long int)> jau::nsize_t

Natural 'size_t' alternative using uint<XX>_t with xx = sizeof(unsigned long int)*8 as its natural sized type, i.e.

either uint32_t (ILP32, LLP64), uint64_t (LP64, ILP64, SILP64) or uint128_t (future).

This is a compromise to indicate intend and to avoid using a multiple sized size_t footprint where not desired.

Note: size_t on LLP64 model is 64-bit, while unsigned long int and hence jau::nsize_t remains 32-bit.
