RtlInt8Add function

-description

Adds two values of type INT8.

-parameters

-param i8Augend [in]

The first value in the equation.

-param i8Addend [in]

The value to add to i8Augend.

-param pi8Result [out]

A pointer to the sum. If the operation results in a value that overflows or underflows the capacity of the type, the function returns STATUS_INTEGER_OVERFLOW and this parameter is not valid.

-returns

Returns STATUS_SUCCESS if the operation is successful.

See the implementation of this helper function in ntintsafe.h in the WDK for possible error return values.

-remarks

This is one of a set of inline functions designed to provide arithmetic operations and perform validity checks with minimal impact on performance.
