A “static” solution (in the sense it can capture a stack trace on demand) would be Process Monitor. A more dynamic solution would be ApiMonitor, but it may be too old to be compatible with the applications to monitor. Worth a try though.
You didn’t mention your prefered programming language, so I’ll use C# for example snippets. You can start a process and capture/write into its standard IO streams. The following snippet, opens a process and captures its StdOut stream: using (var process = Process.Start(new ProcessStartInfo(FileName = @”yourExecutablePath”, UseShellExecute = false, RedirectStandardOutput = true))) using (var stdout = … Read more
You can try my example on hooking the Direct3D 9 API using C#. This utilizes EasyHook an open source .NET assembly that allows you to install hooks from managed code into unmanaged functions. SlimDX is also used – this is an open source managed wrapper around the Direct3D libraries. The tricky part of the hooking … Read more
In the pre-commit hook, the commit message usually hasn’t been created yet 1. You probably want to use one of the prepare-commit-msg or commit-msg hooks instead. There’s a nice section in Pro Git on the order in which these hooks are run, and what you typically might do with them. 1. The exception is that … Read more
Essentially it’s a place in code that allows you to tap in to a module to either provide different behavior or to react when something happens.
This code snippet should intercept SMS messages- You can extend it for other kinds of notifications. Will work on iOS 5.0.1 as well. Does not work with iMessages though. Link with CoreTelephony framework (there are bunch of private headers there which you’d can class-dump) #include <dlfcn.h> #define CORETELPATH “/System/Library/PrivateFrameworks/CoreTelephony.framework/CoreTelephony” id(*CTTelephonyCenterGetDefault)(); void (*CTTelephonyCenterAddObserver) (id,id,CFNotificationCallback,NSString*,void*,int); static void … Read more
The issue is a difference in how Git commands behave in the environment created for hook scripts versus your normal environment. First, hook scripts run with their current working directory set to the Git directory itself (i.e. the .git/ directory of a non-bare repository). Second, hook scripts run with the GIT_DIR environment variable set and … Read more
You install a system wide hook. (SetWindowsHookEx) With this done, you get to be loaded into every process. Now when the hook is called, you look for a loaded d3d9.dll. If one is loaded, you create a temporary D3D9 object, and walk the vtable to get the address of the EndScene method. Then you can … Read more
How to print data from TCP packets Below is an example which does exactly what you need: hook received TCP packets and print their payloads. If you want to print some other information from received packet (like binary data), you just need to modify a bit the section under this comment: /* —– Print all … Read more
The actual commit stuck in by git commit is whatever is in the index once the pre-commit hook finishes. This means that you can change files in the pre-commit hook, as long as you git add them too. Here’s my example pre-commit hook, modified from the .sample: #!/bin/sh # # An example hook script to … Read more
