[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.
