Detailed Description

Configuration macros.

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

Version information:

• CXXOMFORT_DATE - version / date of library release.
• 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:

• CXXOMFORT_ISODATE() - returns the current date of compilation as a YYYYMMDD integer.
• 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
• CXXOMFORT_COMPILER_ID - identifies the compiler detected.
• CXXOMFORT_COMPILER_VERSION - identifies the version of the compiler.

See default-ctor and Behaviour Configuration Macros for other related macros.

CXXOMFORT_CXX14_CODE

#define CXXOMFORT_CXX14_CODE	(		code1,
			code2
	)
