All features described in this document apply to both C and C++ languages. Where a feature is exclusive to one language, or where functionality differs between languages, the following icons are used:

C only
The text describes a feature that is supported in the C language only; or describes behavior that is specific to the C language.
C++ only
The text describes a feature that is supported in the C++ language only; or describes behavior that is specific to the C++ language.
