Detailed Description

Configuration macros.

This section describes the various values that provide information about cxxomfort and the values they can take.

Version information:

• CXXOMFORT_DATE - date of release.
• CXXOMFORT_VERSION - version number (to be deprecated).
• CXXOMFORT_CXX_STD - the year of the C++ Standard running in the compiler.
• CXXOMFORT_CXX_EMULATION - the year of the standard emulated by the compiler.

Informative macros:

• CXXO_STDTR1_NAME() - has the name of the namespace where TR1 names live.
• CXXO_STDTR1_OPEN() , CXXO_STDTR1_CLOSE() - open and close the namespace where TR1 things live

See Code Generation and TYPEDEF charn_t for other related macros.

CXXOMFORT_CXX11_CODE

#define CXXOMFORT_CXX11_CODE	(		code1,
			code2
	)

Evaluates to code1 if at least in C++11 mode, code2 otherwise

Referenced by array_ref< Ch const >::without_back_n().

CXXOMFORT_CXX14_CODE

#define CXXOMFORT_CXX14_CODE	(		code1,
			code2
	)

Evaluates to code1 if at least in C++14 mode, code2 otherwise

CXXOMFORT_CXX17_CODE

#define CXXOMFORT_CXX17_CODE	(		code1,
			code2
	)

Evaluates to code1 if at least in C++17 mode, code2 otherwise

CXXOMFORT_EXCEPTIONS_DISABLED

#define CXXOMFORT_EXCEPTIONS_DISABLED   _undetermined

Evaluates to 1 if exceptions are disabled.

Note

The detection is compiler-dependent.

CXXO_NOEXCEPT

#define CXXO_NOEXCEPT

Evaluates to noexcept when available.

Note

Evaluates to nothing when exceptions are disabled.
