title: What is the semantic inference or meaning of the term "Calli"?
body: <p>I have seen this term in various places in code, such as in <a href="http://code4k.blogspot.com/2011/03/benchmarking-cnet-direct3d-11-apis-vs.html" rel="nofollow" title="see marshaling example with Callivoid&#40;&#41;">graphics programming samples</a>. It seems to be a C++ semantic, but apparently there is a C# / .NET managed implementation called <a href="http://msdn.microsoft.com/en-us/library/system.reflection.emit.ilgenerator.emitcalli%28v=vs.100%29.aspx" rel="nofollow">EmitCalli</a> which seems to be related to <a href="http://msdn.microsoft.com/en-us/library/system.reflection.emit.opcodes.calli%28v=vs.100%29.aspx" rel="nofollow">OpCodes.Calli</a>. I presume this is a machine language instruction. Is there an explanation of this term that is somewhat close to layman's terms?</p>
