breakpoints

I would like to know from where inside a huge application a certain message is printed. The application is so big and old that it uses all conceivable ways of printing text to the terminal; for example printf(), fprintf(stdout, ...) etc. I write to put a breakpoint on the write() system call but then I'm flooded with too many breakpoint stops because of various file I/O operations that use write() as well. So basically I want gdb to stop whenever the program prints something to the terminal but at the same time I don't want gdb to stop when the program writes something to a file. Use a

Regardless of other options that may achieve the same result (i.e. adding breakpoints by hand), is it possible to programmatically add a breakpoint into the source code of a Visual Studio project? Such as: try { FunctionThatThrowsErrors(obj InscrutableParameters); } catch(Exception ex) { Log.LogTheError(ex); AddBreakPointToCallingFunction(); } That way when you run in debug the next time, it will automatically have set breakpoints at all the points that caused trouble during the last run. I'm not saying that's a particularly useful way of debugging. I'm just wondering if the capability is

when developing C++ with VS you have this amazing feature of data breakpoints, which trigger when the data at a certain address in memory changes. is there a similar feature when developing java in eclipse? thanks! edit: about the "suspend when value changes" feature: i have the impression that the execution must still reach the line where the breakpoint is. the thing is i want it to trigger anywhere as soon as the value changes. You can set a watchpoint on a field: put the cursor at the line where the field is being declared and select the menu Run -> Toggle Watchpoint or just set a

Is there a window in Visual Studio 2010 and newer where I can see all the breakpoints that I have in my project or solution? Try Debug -> Windows -> Breakpoints . Tarun Arora Default Shortcuts: To open the break point window: Ctrl + D , B If you wanted to delete all breakpoints: Ctrl + F9 Breakpoints window is not included in some Express versions of Visual Studio. Its included in Pro , Premium , and Ultimate . Here is the manual for the versions : http://msdn.microsoft.com/en-us/library/02ckd1z7%28v=VS.100%29.aspx hima Ctrl + Alt + B in Visual Studio 2010.

How do breakpoints work in C++ code? Are they special instructions inserted in between some assembler instructions when the code is compiled? Or is there something else in place? Also, how are stepping-through-the-code implemented? The same way as breakpoints...? This is heavly depend on the CPU and debugger. For example, one of the possible solution on x86 CPU: Insert one-byte INT3 instruction on the required place Wait until breakpoint exception hits Compare exception address to the list of breakpoint to determine which one Do breakpoint actions Replace INT3 with original byte and switch the

Today I ran into a problem were I needed to remote-debug a program. The program was launched from another system, so I really don't have an opportunity to interact with it on the command line. I could change its source easily though. What I needed to happen was for the program to start normally, and then wait for me to attach to it with a debugger. I couldn't come up with a way to do it that made me happy. I did find the bug, but without the help of the debugger. while(true) { } Kept the process alive, and then I could "set next statement" with the debugger, but it seemed awkward and rude.

Where can I find statistics on mobile and desktop screen sizes? Im making a responsive site and specifically what im trying to find out is weather their is a size gap between the majority of phones and desktop and tablet users where I can put a breakpoint. I think that there should be but know I should test my assumptions. So just to be clear, I want phones to have one set of styles, and tablets and desktops to have another set. Thanks I just finished doing a responsive business website ( https://plus.google.com/101258044853419629282/posts/GejAf734nP6 ) and here is what I can tell you - the

I have a function that is called some large number of times, and eventually segfaults. However, I don't want to set a breakpoint at this function and stop after every time it's called, because I will be here for years. I've heard that I can set a counter in GDB for a breakpoint, and each time the breakpoint is hit, the counter is decremented, and only gets triggered when the counter = 0. Is this accurate, and if so how do I do it? Please give the gdb code for setting such a breakpoint. Kilian Foth Read section 5.1.6 of the GDB manual. What you have to do is first set a breakpoint, then set an

How do I automatically set breakpoints on all methods in Xcode? I want to know how my program works, and which methods invoke when I interact with the user interface. Run your app in Xcode. Press ⌘⌃Y (Debug -> Pause). Go to the debugger console: ⌘⇧C Type breakpoint set -r . -s <PRODUCT_NAME> (insert your app's name). lldb will answer with something like... Breakpoint 1: 4345 locations Now just press the Continue button. breakpoint set is lldb's command to create breakpoints. The location is specified using a regular expression ( -r ) on function/method names, in this case . which matches any
