The header <limits.h> defines several macros that expand to various limits and
|
|
parameters of the standard integer types.
|
|
|
|
The values given below are constant expressions suitable for
|
|
use in #if preprocessing directives. Except for CHAR_BIT and
|
|
MB_LEN_MAX, they have the same
|
|
type as would an expression that is an object of the corresponding type
|
|
converted according to the integer promotions.
