random technical notes

stdint.h is a header file in the C standard library introduced in the C99 standard library section 7.18 to allow programmers to write more portable code by providing a set of typedefs that specify exact-width integer types, together with the defined minimum and maximum allowable values for each type, using macros. This header is particularly useful for embedded programming which often involves considerable manipulation of hardware specific I/O registers requiring integer data of fixed widths, specific locations and exact alignments. stdint.h (for C), and stdint.h and cstdint (for C++).

stdint.h defines:

int8_t
int16_t
int32_t
uint8_t
uint16_t
uint32_t

stdint.h is not shipped with older C++ compilers and Visual Studio C++ products prior to Visual Studio 2010.
