- [section:vmd_internal_macros Controlling internal usage]
- VMD has a few object-like macros which the end-user of the library can use
- to determine or change the way variadic macros are used in the library.
- The macro BOOST_PP_VARIADICS is part of the Boost PP library, not part of VMD.
- It is used to denote whether variadic data support exists for the particular compiler
- the end-user is using. VMD also uses this macro to determine whether variadic
- data support exists. An end-user of VMD can use this macro in his own design
- to determine whether or not variadic macros are supported. Furthermore
- an end-user of VMD can set this macro to 0 or non-zero, before including
- a VMD header file, to force VMD to treat the particular compiler being
- used as not supporting or supporting variadic macros. If a compiler does
- not support variadic macro none of the macros in VMD are defined.
- The macro BOOST_VMD_ASSERT_DATA controls whether or not an assert macro
- will check its data. The default is that in compiler debug mode it will check the
- data while in compiler release mode it will not check its data. The end-user can
- change this by setting the macro to 0 to not check the data, or non-zero to check
- the data, before including a VMD header file, or check the value if necessary after
- including a VMD header file.
