Macro Definition Documentation

OMW__FILENAME__

#define OMW__FILENAME__

since C++14

Returns the filename of the current file as const char*. Similar to __FILE__, but does not contain the full path.

OMW_CPPSTD

#define OMW_CPPSTD

Used to compare to OMW_CPPSTD_xx.

If MSVC is used it's defined as an alias for the MSVC specific macro _MSVC_LANG, otherwise it's an alias for __cplusplus.

OMW_CPPSTD_23

#define OMW_CPPSTD_23   (202100L)

C++23 isn't released yet. Thus the value may change in the future!

The current value is from GCC 11.1.0

OMW_DEBUG

#define OMW_DEBUG   (1)

Defined as 1 if _DEBUG is defined, otherwise undefined.

OMW_PLAT_POSIX

#define OMW_PLAT_POSIX   (1)

Defined as 1 if the Unix is POSIX compliant, otherwise undefined.

OMW_PLAT_WIN

#define OMW_PLAT_WIN   (1)

Defined as 1 if OMW_PLAT_WIN32 or OMW_PLAT_WIN64 is defined, otherwise undefined.

OMW_PLAT_WIN32

#define OMW_PLAT_WIN32   (1)

Defined as 1 if target is 32-bit Windows, otherwise undefined.

OMW_PLAT_WIN64

#define OMW_PLAT_WIN64   (1)

Defined as 1 if target is 64-bit Windows, otherwise undefined.

OMW_VERSION_ID

#define OMW_VERSION_ID   (5)

Uniqe version ID, always greater than the ID of the last version.

Can be compared to OMW_VERSION_ID_..

Version	Version ID
v0.2.0	1
v0.2.1-alpha	2
v0.2.1-alpha.1	3
v0.2.1-alpha.2	4
v0.2.1-beta	5
