C++ question: What does the keyword "using" mean here? template <class DeviceClass> using required_device = device_finder<DeviceClass, true>; Found here:https://github.com/mamedev/mame/blob/83b3a2e0e5d6ac8bf1bc76cd7b3c98273dff4259/src/emu/devfind.h#L673 …
It is basically a typedef brother. "The identifier following the using keyword becomes a typedef-name and the optional attribute-specifier-seq following the identifier appertains to that typedef-name." - https://timsong-cpp.github.io/cppwp/n4659/dcl.typedef#2 …pic.twitter.com/Fmn1KNs1wa
