Calling Functions: A Tutorial
Books by Klaus Iglberger
Klaus Iglberger gives a training: C++ Software Design
Klaus Iglberger
On Day 3 at (CET/Berlin) in Track A [Saphir Room and online]
How is a function call resolved? How does the compiler find the right function and how does the compiler choose from a set of available functions? This talk will give an overview of the individual steps taken during the resolution of a function call. It will primarily focus on the different kinds of name lookup, argument deduction, and on overload resolution. Attendees will gain insight into the mechanics of (un-)qualified lookup, argument dependent lookup, two-phase lookup, name hiding, SFINAE, (viable) candiate functions, and ambiguous function calls. They will leave the talk with a much better understanding of the (sometimes surprising) details of function calls.
