Optional breakpoint parameters

Optional breakpoint parameters are used to control the behavior of breakpoints. You can set the following parameters when you set a breakpoint:

Optional breakpoint parameter Description Type of breakpoint supported
Threads This selection list lets you choose what threads to set the breakpoint in. To select a thread ID from the list, highlight the thread where you want to set the breakpoint. This list is available only on platforms that support multithreaded programs. This parameter is supported by all breakpoint types.
Frequency Use the Frequency controls to tell the debugger when to stop on a breakpoint and when to skip it. The debugger keeps track of how many times each breakpoint is encountered. The fields in this section tell the debugger on which encounter of a breakpoint the debugger should first stop, how often it should stop, and on which encounter the debugger should no longer stop.

The following parameters are used to set the breakpoint frequency:

From Enter the first breakpoint encounter you want the debugger to stop on. For example, if you want the debugger to skip over the breakpoint the first five times it is encountered, enter "6".
To Enter the last breakpoint encounter you want the debugger to stop on. For example, if you want it to start ignoring the breakpoint after the 20th encounter, enter "20". To have it always stop on the breakpoint, enter "Infinity".
Every Enter the frequency with which you want the debugger to stop on this breakpoint. For example, if you want it to stop on only one out of every four it encounters, enter "4".
This parameter is supported by all breakpoint types.
Expression You can enter an expression into this field. The execution of the program stops at the breakpoint only if the condition specified in this field tests true.

For example, if you are debugging a C++ program you could type the following:

(i==1) || (j==k) && (k!=5)

Line, function or method
Defer Select this check box if you want to set a breakpoint in a program module that is not currently loaded.

If you enter an incorrect source, file, function, or program unit, the debugger will not be able to activate the breakpoint when the program is loaded, and the breakpoint will remain in the deferred state.

Restriction: You cannot set a deferred breakpoint in a preloaded DLL or dynamically called routine, but you can set one in a program that has some preloaded DLLs or dynamically called routines and some dynamically loaded ones.
