Class SBBreakpoint

source code

Represents a logical breakpoint and its associated settings.

For example (from test/functionalities/breakpoint/breakpoint_ignore_count/
TestBreakpointIgnoreCount.py),

    def breakpoint_ignore_count_python(self):
        '''Use Python APIs to set breakpoint ignore count.'''
        exe = os.path.join(os.getcwd(), 'a.out')

        # Create a target by the debugger.
        target = self.dbg.CreateTarget(exe)
        self.assertTrue(target, VALID_TARGET)

        # Now create a breakpoint on main.c by name 'c'.
        breakpoint = target.BreakpointCreateByName('c', 'a.out')
        self.assertTrue(breakpoint and
                        breakpoint.GetNumLocations() == 1,
                        VALID_BREAKPOINT)

        # Get the breakpoint location from breakpoint after we verified that,
        # indeed, it has one location.
        location = breakpoint.GetLocationAtIndex(0)
        self.assertTrue(location and
                        location.IsEnabled(),
                        VALID_BREAKPOINT_LOCATION)

        # Set the ignore count on the breakpoint location.
        location.SetIgnoreCount(2)
        self.assertTrue(location.GetIgnoreCount() == 2,
                        'SetIgnoreCount() works correctly')

        # Now launch the process, and do not stop at entry point.
        process = target.LaunchSimple(None, None, os.getcwd())
        self.assertTrue(process, PROCESS_IS_VALID)

        # Frame#0 should be on main.c:37, frame#1 should be on main.c:25, and
        # frame#2 should be on main.c:48.
        #lldbutil.print_stacktraces(process)
        from lldbutil import get_stopped_thread
        thread = get_stopped_thread(process, lldb.eStopReasonBreakpoint)
        self.assertTrue(thread != None, 'There should be a thread stopped due to breakpoint')
        frame0 = thread.GetFrameAtIndex(0)
        frame1 = thread.GetFrameAtIndex(1)
        frame2 = thread.GetFrameAtIndex(2)
        self.assertTrue(frame0.GetLineEntry().GetLine() == self.line1 and
                        frame1.GetLineEntry().GetLine() == self.line3 and
                        frame2.GetLineEntry().GetLine() == self.line4,
                        STOPPED_DUE_TO_BREAKPOINT_IGNORE_COUNT)

        # The hit count for the breakpoint should be 3.
        self.assertTrue(breakpoint.GetHitCount() == 3)

        process.Continue()

SBBreakpoint supports breakpoint location iteration, for example,

    for bl in breakpoint:
        print 'breakpoint location load addr: %s' % hex(bl.GetLoadAddress())
        print 'breakpoint location condition: %s' % hex(bl.GetCondition())

and rich comparion methods which allow the API program to use,

    if aBreakpoint == bBreakpoint:
        ...

to compare two breakpoints for equality.
