NAME

       stdint - integer types

SYNOPSIS

DESCRIPTION

       This header file defines sets of integer types having specified widths and corresponding sets of macros.  It also defines macros that spec-
       ify limits of integer types corresponding to types defined in other standard headers.

       Since not all implementations are required to support all of the integer sizes defined in this manual page, the proper way to see if a par-
       ticular	size  of an integer is supported on the current implementation is to test the symbol that defines its maximum value.  For example,
       if tests false, then that implementation does not support 64-bit unsigned signed integers.

       This header file defines the following integer data types for 8, 16, 32, and 64 bits.

	      largest signed integer data type supported by implementation

	      8-bit signed integer

	      16-bit signed integer

	      32-bit signed integer

	      64-bit signed integer

	      largest unsigned integer data type supported by implementation

	      8-bit unsigned integer

	      16-bit unsigned integer

	      32-bit unsigned integer

	      64-bit unsigned integer

       The following two data types are signed and unsigned integer data types that are large enough to hold a pointer.  A pointer can be moved to
       or from these data types without corruption.

	      signed integer type that is large enough to hold a pointer

	      unsigned integer type that is large enough to hold a pointer

       This header file defines the following integer data types for determining the most efficient data types to use for integer values on a par-
       ticular implementation.

	      most efficient signed integer data type supported by implementation

	      most efficient signed integer of at least 8 bits

	      most efficient signed integer of at least 16 bits

	      most efficient signed integer of at least 32 bits

	      most efficient signed integer of at least 64 bits

	      most efficient unsigned integer data type supported by implementation

	      most efficient unsigned integer of at least 8 bits

	      most efficient unsigned integer of at least 16 bits

	      most efficient unsigned integer of at least 32 bits

	      most efficient unsigned integer of at least 64 bits

       This header file defines the following integer data types for compatibility with systems that do not fit the 16-bit  or	32-bit	word  size
       model.  These data types define the signed and unsigned integers of at least 8, 16, 32, and 64 bits.

	      smallest signed integer of at least 8 bits

	      smallest signed integer of at least 16 bits

	      smallest signed integer of at least 32 bits

	      smallest signed integer of at least 64 bits

	      smallest unsigned integer of at least 8 bits

	      smallest unsigned integer of at least 16 bits

	      smallest unsigned integer of at least 32 bits

	      smallest unsigned integer of at least 64 bits

       The following macros define the minimum and maximum values that can be stored in the above data types.

	      minimum value that can be stored in the largest integer data type

	      maximum value that can be stored in the largest signed integer data type

	      maximum value that can be stored in the largest unsigned integer data type

				    integer data type

       The following macros specify the maximum and minimum limits of integer types corresponding to types defined in other standard headers.  All
       these values are implementation defined.

       The following macros expand to integer constant expressions suitable for initializing objects that  have  integer  types  corresponding	to
       types defined in header.

   Macros For Minimum-Width Integer Constant Expressions
       The macro expands to an integer constant expression corresponding to the type

       The  macro  expands to an integer constant expression corresponding to the type For example, if is a name for the type then might expand to
       the integer constant

   Macros For Greatest-Width Integer Constant Expressions
       The following macro expands to an integer constant expression having the value specified by its argument and the type
