In C, a programmer must manually manage adding and removing references, but in Vala, managing such reference counts is automated if a programmer uses the language's built-in reference types rather than plain pointers. The only detail one needs to worry about is to avoid generating 855:-based libraries, without the need for runtime bindings. To use a library with Vala, all that needed is an API file (.vapi) containing the class and method declarations in Vala syntax. However, C++ libraries are not supported. At present, vapi files for a large part of the 874:
It should also be easily possible to write a bindings generator for access to Vala libraries from applications written in other languages, e.g., C#, as the Vala parser is written as a library, so that all compile-time information is available when generating a binding.

functions are registered to the signal of an instance of the class. The instance can emit the signal and each callback function (also referred to as handler) connected to the signal for the instance will get invoked in the order they were connected in:
334:. Writing these interface definitions is well-documented for C libraries. Bindings are already available for a large number of libraries, including libraries that are not based on GObject such as the multimedia library 2693:
The Vala compiler also supports the Genie language, which is almost equal to Vala except the syntax. That is useful especially for defining models because of simple, "Python-like" syntax of Genie.
