/** @file
|
||
|
|
The header <limits.h> defines several macros that expand to various limits and
|
||
|
|
parameters of the standard integer types.
|
||
|
|
|
||
|
|
The values given below shall be replaced by constant expressions suitable for
|
||
|
|
use in #if preprocessing directives. Moreover, except for CHAR_BIT and
|
||
|
|
MB_LEN_MAX, the following shall be replaced by expressions that have the same
|
||
|
|
type as would an expression that is an object of the corresponding type
|
||
|
|
converted according to the integer promotions. Their implementation-defined
|
||
|
|
values shall be equal or greater in magnitude (absolute value) to those
|
||
|
|
documented, with the same sign.
|
||
|
|
|
||
|
|
If the value of an object of type char is treated as a signed integer when
|
||
|
|
used in an expression, the value of CHAR_MIN shall be the same as that of
|
||
|
|
SCHAR_MIN and the value of CHAR_MAX shall be the same as that of SCHAR_MAX.
|
||
|
|
Otherwise, the value of CHAR_MIN shall be 0 and the value of CHAR_MAX shall
|
||
|
|
be the same as that of UCHAR_MAX.)
|
||
|
|
The value UCHAR_MAX shall equal 2^(CHAR_BIT - 1).
