The limits header defines the characteristics of
variable types.
Defined Values
The following values are defined with the
#define directive. These values are
implementation-specific, but may not be any lower than what
is given here.
CHAR_BIT 8
|
Number of bits in a byte.
|
SCHAR_MIN -127
|
Minimum value for a signed char.
|
SCHAR_MAX +127
|
Maximum value for a signed char.
|
UCHAR_MAX 255
|
Maximum value for an unsigned char.
|
CHAR_MIN
CHAR_MAX
|
These define the minimum and maximum values for
a char. If a char is being represented as a signed
integer, then their values are the same as the
signed char (SCHAR) values.
Otherwise CHAR_MIN is 0 and
CHAR_MAX is the same as
UCHAR_MAX.
|
MB_LEN_MAX 1
|
Maximum number of bytes in a multibyte
character.
|
SHRT_MIN -32767
|
Minimum value for a short int.
|
SHRT_MAX +32767
|
Maximum value for a short int.
|
USHRT_MAX 65535
|
Maximum value for an unsigned short int.
|
INT_MIN -32767
|
Minimum value for an int.
|
INT_MAX +32767
|
Maximum value for an int.
|
UINT_MAX 65535
|
Maximum value for an unsigned int.
|
LONG_MIN -2147483647
|
Minimum value for a long int.
|
LONG_MAX +2147483647
|
Maximum value for a long int.
|
ULONG_MAX 4294967295
|
Maximum value for an unsigned long int. |
