X-Hacker.org- Programmers Reference 0.02b - <b>int 04h overflow</b> http://www.X-Hacker.org [<<Previous Entry] [^^Up^^] [Next Entry>>] [Menu] [About The Guide]
INT 04h           Overflow

    Called when either an INTO (Interrupt on Overflow) instruction is
    encountered and the Overflow Flag (OF) is set, or when an INT 4
    instruction is encountered.

    This service gives programmers a way to provide a common handler for
    all arithmetic overflow conditions. By executing an INTO instruction
    after any arithmetic operation, a program can ensure that overflow
    conditions are properly handled.
