The BOOST_PP_TUPLE_POP_FRONT macro pops an element from the beginning of a tuple.

Usage

BOOST_PP_TUPLE_POP_FRONT(tuple) (v)

Arguments

tuple
The tuple to pop an element from.

Remarks

This macro returns tuple after removing the first element.  If tuple has only a single element, it remains unchanged since a tuple must have at least one element.
This macro uses BOOST_PP_REPEAT internally.  Therefore, to use the z parameter passed from other macros that use BOOST_PP_REPEAT, see BOOST_PP_TUPLE_POP_FRONT_Z
