Description

The macro checks that the parameter is a pplib array. If it is not a pplib array, it forces a compiler error.

The macro works through variadic macro support.

The macro normally checks for a pplib array only in debug mode. However an end-user can force the macro to check or not check by defining the macro BOOST_VMD_ASSERT_DATA to 1 or 0 respectively.

array = a possible pplib array.

returns = Normally the macro returns nothing. If the parameter is a pplib array, nothing is output. For VC++, because there is no sure way of forcing a compiler error from within a macro without producing output, if the parameter is not a pplib array the macro forces a compiler error by outputting invalid C++. For all other compilers a compiler error is forced without producing output if the parameter is not a pplib array.
