2.5.1 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 | 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. |
