Files limits(4)
CHAR_BIT Number of bits in an object of type char. This value is always 8.
CHARCLASS_NAME_MAX
Maximum number of bytes in a character class name. This value is always 255.
CHAR_MAX Maximum value for a signed char. In the HP implementation, the type
char is
not considered a signed integer; CHAR_MAX is therefore treated like
UCHAR_MAX.
CHAR_MIN Minimum value for a signed char. In the HP implementation, the type
char is
not considered a signed integer; CHAR_MIN is therefore 0 (zero).
COLL_WEIGHTS_MAX
Maximum number of weights that can be assigned to an entry of the
LC_COLLATE order keyword in the locale definition file. This is a runtime-
increasable value. Use the sysconf() function to obtain the runtime value.
EXPR_NEST_MAX
Maximum number of expressions that can be nested within parentheses by the
expr utility. This is a runtime-increasable value. Use the sysconf() function to
obtain the runtime value.
INT_BIT Number of bits in an object of type int. In the HP implementation, this value is
32.
INT_MAX Maximum value for an object of type int. This value depends on the size of an
integer, which, in the HP implementation, is 32 bits.
INT_MIN Minimum value for an object of type int. This value depends on the size of an
integer, which, in the HP implementation, is 32 bits.
LINE_MAX Unless otherwise noted, the maximum length, in bytes, of the input line to a util-
ity (from either the standard input file or another file), when the utility is
described as processing text files. The length includes room for the trailing new-
line character. This is a runtime-increasable value. Use the sysconf() function
to obtain the runtime value.
LLONG_BIT Number of bits in an object of type long long int. This symbolic constant is
specific to the HP implementation.
LLONG_MAX
Maximum value for an object of type long long int. This symbolic constant is
specific to the HP implementation.
LLONG_MIN Minimum value for an object of type long long int. This symbolic constant is
specific to the HP implementation.
LONG_BIT Number of bits in an object of type long int.
LONG_MAX Maximum value for an object of type long int.
LONG_MIN Minimum value for an object of type long int.
MB_LEN_MAX
Maximum number of bytes in a character for any supported locale.
