= BDLB_SCOPEEXIT_USES_MODERN_CPP
:mrdocs:

This macro determines if we have a sufficiently functional C++11 or later compiler so the type‐deducing `auto` with factory‐method can be compiled and works as expected. When the macro is not defined (C++03 form) no utility `struct` (therefore no factory method) will be defined by this component and the variable definition macros (for Proctor and Guard) will use `bdlb::ScopeExitAny`. When this macro is defined (C++11 or later that has sufficiently operation rvalue references and type‐deducing `auto` keyword implementation) the factory method and its utility `struct` will be defined and the variable definition macros will use `auto` to determine the type of the `bdlb::ScopeExit` variable. This macro is only internally in this component header and therefore it is undefined at the end of the file.
