DESCRIPTION
The check_<type>_<operation>(x, y, err) family of functions perform the specified arithmetic operation (addition, subtraction, multiplica-
tion, or division) with the left operand of x and right operand of y and return the arithmetic result with the specified type.
Either operand x or y (or both) can be of any type that is compatible to signed or unsigned 8-bit, 16-bit, 32-bit, or 64-bit integers.
The err argument is or'ed by flags in the function to indicate if an overflow has occurred. The possible flag values are:
CHECKINT_NO_ERROR no overflow has occurred
CHECKINT_OVERFLOW_ERROR overflow has occurred
CHECKINT_TYPE_ERROR operand is of an incompatible type
The err argument is not cleared in calls to the check_<type>_<operation>(x, y, err) functions. Detected overflow persists in the err argu-
ment until err is reset to CHECKINT_NO_ERROR.
RETURN VALUES
If successful, the check_<type>_<operation>() functions will return the arithmetic result of performing the operation with left operand x and
right operand y (even when overflow error occurs).
If any other error occurs, the return value is -1 and the argument err will be set to indicate the error.
EXAMPLES
/* Create a variable to store overflow flag */
int32_t err = CHECKINT_NO_ERROR;
/* Use checkint API to perform an arithmetic operation and
* store result in variable. */
int32_t arithmetic_result = check_int32_add(UINT_MAX, 1, &err);
/* Check status of overflow flag */
if (err & CHECKINT_OVERFLOW_ERROR) {
/* Perform overflow resolution code */
fprintf(stderr, "Overflow detected!
");
}
/* Check for type error */
else if (err & CHECKINT_TYPE_ERROR) {
/* Deal with incompatible types error */
fprintf(stderr, "Incompatible types!
");
}
/* Reset overflow flag for next operation */
err = CHECKINT_NO_ERROR;
ERRORS
The check_<type>_<operation>() functions may fail if:
[CHECKINT_TYPE_ERROR] operand is of an incompatible type
HISTORY
The checkint() API was introduced in Mac OS X 10.5.
