    NAME

    
    
    stdint
    
     - standard integer types
    
     
    

    SYNOPSIS

       #include <stdint.h>
     

    DESCRIPTION

    The    #include <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 Vt int8_t , Vt int16_t , Vt int32_t , and Vt int64_t provide a signed integer type of width 8, 16, 32, or 64 bits, respectively. The types Vt uint8_t , Vt uint16_t , Vt uint32_t , and Vt uint64_t provide 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 Vt int_fast8_t , Vt int_fast16_t , Vt int_fast32_t , and Vt int_fast64_t provide the fastest signed integer type with a width of at least 8, 16, 32, or 64 bits, respectively. The types Vt uint_fast8_t , Vt uint_fast16_t , Vt uint_fast32_t , and Vt 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 Vt int_least8_t , Vt int_least16_t , Vt int_least32_t , and Vt int_least64_t provide the smallest memory footprint signed integer type with a width of at least 8, 16, 32, or 64 bits, respectively. The types Vt uint_least8_t , Vt uint_least16_t , Vt uint_least32_t , and Vt 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 Vt intmax_t provides a signed integer type large enough to hold any other signed integer. The type Vt 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 Vt intptr_t provides a signed integer type with the ability to hold a pointer to Vt void , that can later be converted back to a pointer to Vt void .

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

    Additionally, the    #include <stdint.h>
    header defines some macros, but none of them are documented here.  

    STANDARDS

    The    #include <stdint.h>
    header conforms to St -isoC-99 and St -p1003.1-2001 .  

    HISTORY

    The    #include <stdint.h>
    header was first introduced in Fx 5.0 .
