All uses of Ellipsis in C++

Question

Currently, I could recollect only three uses of ... in C++:

1. variadic functions
2. variadic templates
3. catch block

I tried different ways of googling "all uses of ellipsis in C++" but failed to find it. I am focussing on the current standard of C++.

Answer 1

That's pretty much it, besides variadic macros mentioned in the comments. I made a grouped tree list:

• Variadic
  • Template parameter packs
    • Template parameter delcaration
    • Function parameter declaration
    • Parameter pack expansions (these can be in many contexts)
      • Plain variadic expansion (can be used in declarations)
      • Fold expressions
      • Variadic sizeof
  • C style variadic parameters
  • Variadic macros
• Catch all
