Macro Definition Documentation

VU_API

#define VU_API   __attribute__((visibility("default")))

Platform-specific preprocessor definitions.

Define exporting / importing of functions from module

VU_ENUM

#define VU_ENUM

(

_type

)

Value:

    typedef int32_t _type; \
    enum

Cross-platform macro for storing the value of the C++ language standard targeted by the compiler as an integer literal.

Note

The MSVC compiler does not conform to the C++ standard regarding the __cplusplus macro. Unless the /Zc:__cplusplus compiler option is enabled in Visual Studio 2017 v15.7 or above, the __cplusplus macro always reports 199711L (C++98). The _MSVC_LANG macro stores the expected C++ language standard value in Visual Studio 2015 Update 3 and above.

Macro for defining enums

Note

In order to enforce the size of the enum type for ABI compatibility, use the underlying type feature of enums if the compiler is targeting C++11 and above, otherwise use int32_t for fixed size.

VU_CONST_INT

#define VU_CONST_INT	(		name,
			value )

Value:

    enum                          \
    {                             \
        name = value              \
    }

Macro for defining a compile-time integer constant.
