Can I omit unused argument names? - No, you can't. - Fine, but then you won't complain if I don't use them, right? - Oh you bet I will.

-    Before the 23 standard, C and C++ handled unused arguments differently.
-    C does not allow variable names to be omitted, but does not complain if
-    the variable is unused. On the other hand, C++ allows variable names to
-    be omitted, but will complain if it is not used when named.
-    The "[[maybe_unused]]" attribute is a C23 extension, so it's not applicable
-    here until support for earlier standards is dropped.
