Method stub

<h2 id="example">Example</h2>
<p>In the following example <a href="/facts/Pseudocode/XgN19duK">pseudocode</a>, the function ReadThermometer returns a particular value even though ultimately it is supposed to read a value from a <a href="/facts/Electronic_hardware/fKcrTv2f">hardware</a> source. It returns a valid value, allowing consuming code to be runnable. The function ignores the input <a href="/facts/Parameter_(computer_science)/LcuLbbSq">parameter</a> source which is common for a stub.
</p>
function ReadThermometer(Source source)
    return 28
end function

<h3>Distributed computing</h3>
<p>In <a href="/facts/Distributed_computing/o5nyhqTF">distributed computing</a>, <i>stub</i> is like a <a href="/facts/Mock_object/KGPLkPpV">mock object</a> – <a href="/facts/Simulation/Q4QJV1oI">simulates</a> existing code, such as a <a href="/facts/Subroutine/9vFJrg0A">procedure</a> on a remote machine. Such stubs can be useful in <a href="/facts/Porting/7s6tFs8B">porting</a>.

<p>In <a href="/facts/Windows/bwhAhuSL">Windows</a> and <a href="/facts/DOS/sWwDXNmX">DOS</a>, <i>stub</i> is like a <a href="/facts/Shim_(computing)/LRz0gdKm">shim</a> – small interface code left in <a href="/facts/Conventional_memory/hLcfWzlB">conventional memory</a> by <a href="/facts/Self-relocation/gMw61ATA">self-relocating</a> resident drivers which move most of themselves into <a href="/facts/Upper_memory/CLE38IvM">upper memory</a>, the <a href="/facts/High_memory_area/NPW4zCVl">high memory area</a>, <a href="/facts/Expanded_memory/cYurvMxB">expanded</a> or <a href="/facts/Extended_memory/WoJJj268">extended memory</a> as well as similar stubs to allow the relocated code to communicate with <a href="/facts/Real-mode/wfU8vfjn">real-mode</a> DOS in conjunction with <a href="/facts/DOS_extender/fhzoAhzm">DOS extenders</a> (like <a href="/facts/DOS_Protected_Mode_Interface/5lWQW6bI">DPMI</a>, <a href="/facts/DOS_Protected_Mode_Services/1bt44EVm">DPMS</a>, <a href="/facts/CLOAKING_(DOS_extender)/1bt44EVm">CLOAKING</a> or <a href="/facts/NetWare_I%2fO_Subsystem/1bt44EVm">NIOS</a>).
