Listing of support macros

The following macros determine what features does cxxomfort implement and whether it does so by forwarding to native facilities or by providing its own forms of emulation.

The possible values for these macros are:

• CXXO_IMPLSTATUS_NATIVE() – cxxomfort doesn't do anything; instead, the compiler's native facility is in use.
• CXXO_IMPLSTATUS_BACKPORT() – cxxomfort provides a backport of the given feature, using other facilities either already native or existing in cxxomfort.
• CXXO_IMPLSTATUS_EMULATION() – cxxomfort provides an alternative or emulation of the given feature that differs in syntax, semantics and capabilities; most likely using a different name.
• 0 – the feature is not supported, or the required header has not been included.

cxxomfort implementation macro	related __cpp macros	Notes
CXXOMFORT_IMPLEMENTS_static_assert	__cpp_static_assert	Has a value other than 0 if the library implements static_assert. Has a value greater than 0 if the extension static_assert0 (omit message) is supported.
CXXOMFORT_IMPLEMENTS_foreach	__cpp_range_based_for	Has a value other than 0 if the library implements foreach loop emulation (see CXXO_FOREACH() ).
