Thunk (original) (raw)
In computer programming, a thunk is a subroutine used to inject a calculation into another subroutine. Thunks are primarily used to delay a calculation until its result is needed, or to insert operations at the beginning or end of the other subroutine. They have many other applications in compiler code generation and modular programming. The term originated as a whimsical irregular form of the verb think. It refers to the original use of thunks in ALGOL 60 compilers, which required special analysis (thought) to determine what type of routine to generate.

| dbo:abstract | Als Thunk bezeichnet man im Jargon der Softwareentwicklung den Aufruf von Code, der einer anderen Plattform oder einem anderen Framework angehört. Bei der Umstellung von 16 auf 32 Bit beispielsweise konnten die Betriebssysteme (OS/2, Windows NT etc.) 16-Bit-Code durch entsprechendes Umsetzen der Aufrufparameter und Adressen realisieren, so dass 16-Bit-Programme weiter verwendet werden konnten. In der modernen Softwareentwicklung ist ein Thunk z. B. der Aufruf von nativem Code aus Managed Code heraus und umgekehrt (siehe Java Native Access oder .Net-Frameworks P/Invoke). Es handelt sich also um einen Plattform-Übergang (Transition), bei dem die Aufrufkonventionen und/oder Übergabeparameter entsprechend umgesetzt werden müssen (Marshalling). Die Programmiersprache C++/CLI aus dem .NET-Framework von Microsoft wurde eigens dazu konzipiert, solche Thunks in beide Richtungen zu ermöglichen: (de) Thunk es un término usado en la jerga del desarrollo de software que designa la llamada o invocación a un código que pertenece a otra plataforma o a otro Framework. En el paso de 16 a 32 bit por ejemplo, los sistemas operativos (OS/2, Windows NT etc.) podían resolver código de 16 bit a través de la transformación de los parámetros de llamadas y direcciones, de modo tal que fue posible seguir utilizando los programas de 16 bit. En el desarrollo de software moderno, un thunk es la llamada del código nativo desde el código gestionado y viceversa (véase por ejemplo Java Native Access o .NET P/Invoke). Es decir, se trata de una plataforma de transición, en la que las convenciones y/o parámetros de invocación tienen que transformarse correspondientemente (Marshalling). El lenguaje de programación C++/CLI del .NET-Framework de Microsoft fue concebido especialmente para posibilitar tales thunks en ambas direcciones: (es) In computer programming, a thunk is a subroutine used to inject a calculation into another subroutine.
