\brief Determines if a sequence is a Boost pplib list.
|
||
|
|
|
||
|
|
The macro checks that the sequence is a pplib list.
|
||
|
|
It returns 1 if it is a list, else if returns 0.
|
||
|
|
|
||
|

sequence = input as a possible Boost PP list.

|
|
|
||
|
|
returns = 1 if it a list, else returns 0.
|
||
|
|
|
||
|
|
The macro will generate a preprocessing error if the input
|
||
|
|
is in the form of a list but its end-of-list marker, instead
|
||
|
|
of being an identifier, is a preprocessor token which VMD cannot parse,
|
||
|
|
as in the example '(anything,&BOOST_PP_NIL)' which is a valid tuple but
|
||
|
|
an invalid list.
