NetBSD 6.1.5 - man page for stdint (netbsd section 3)

STDINT(3)			   BSD Library Functions Manual 			STDINT(3)

NAME
     stdint -- standard integer types

SYNOPSIS
     #include <stdint.h>

DESCRIPTION
     The <stdint.h> header provides source-portable integer types of a specific size, smallest
     memory footprint with a minimum size, fastest access speed with a minimum size, largest
     integer size, and those capable of storing pointers.

     The types int8_t, int16_t, int32_t, and int64_t provide a signed integer type of width 8,
     16, 32, or 64 bits, respectively.	The types uint8_t, uint16_t, uint32_t, and uint64_t pro-
     vide an unsigned integer type of width 8, 16, 32, or 64 bits, respectively.  These integer
     types should be used when a specific size is required.

     The types int_fast8_t, int_fast16_t, int_fast32_t, and int_fast64_t provide the fastest
     signed integer type with a width of at least 8, 16, 32, or 64 bits, respectively.	The types
     uint_fast8_t, uint_fast16_t, uint_fast32_t, and uint_fast64_t provide the fastest unsigned
     integer type with a width of at least 8, 16, 32, or 64 bits, respectively.  These types
     should be used when access speed is paramount, and when a specific size is not required.

     The types int_least8_t, int_least16_t, int_least32_t, and int_least64_t provide the smallest
     memory footprint signed integer type with a width of at least 8, 16, 32, or 64 bits, respec-
     tively.  The types uint_least8_t, uint_least16_t, uint_least32_t, and uint_least64_t provide
     the smallest memory footprint unsigned integer type with a width of at least 8, 16, 32, or
     64 bits, respectively.  These types should be used when memory storage is of concern, and
     when a specific size is not required.

     The type intmax_t provides a signed integer type large enough to hold any other signed inte-
     ger.  The type uintmax_t provides an unsigned integer type large enough to hold any other
     unsigned integer.	These types are generally the largest signed and unsigned integer types
     available on a specific architecture.

     The type intptr_t provides a signed integer type with the ability to hold a pointer to void,
     that can later be converted back to a pointer to void.

     The type uintptr_t provides an unsigned integer type with the ability to hold a pointer to
     void, that can later be converted back to a pointer to void.

STANDARDS
     The <stdint.h> header conforms to ISO/IEC 9899:1999 (``ISO C99'') and IEEE Std 1003.1-2001
     (``POSIX.1'').

HISTORY
     The <stdint.h> header was first introduced in NetBSD 1.6.
