The BOOST_PP_ARRAY_POP_FRONT macro pops an element from the beginning of an array.

Usage

BOOST_PP_ARRAY_POP_FRONT(array)

Arguments

array
The array to pop an element from.

Remarks

This macro returns array after removing the first element.  If array has no elements, the result of applying this macro is undefined.
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_ARRAY_POP_FRONT_Z
