Fam++ is a software tool that provides a C++ wrapper for fam, facilitating efficient file monitoring and change detection.
Fam++ is equipped with two main classes that efficiently access fam. The first class is quite basic, while the second one uses gdk to register callbacks automatically and dispatch fam events to functors that are set up. Additionally, the gdk fam can display a gnomeMessageBox if fam is not available and ensures that it continues to look for fam while the dialog is open, meaning that the user doesn't need to interact with the dialog if fam does become available.
Users are provided with example code in the main distribution to help them access fam++ from a console app and a GTK+ application. However, it is essential to note that Fam++ is currently in the alpha stage. Although the API is expected to be stable and okay, developers are yet to provide enough feedback to ascertain if there are any issues with the API.
Fam++ has proven to be beneficial as it has been used in gpdial_applet, providing another example of its usage. Overall, Fam++ boasts of excellent features designed to simplify software development, making it a must-have for every developer.
