BOOST_PP_ARRAY_REMOVE

The BOOST_PP_ARRAY_REMOVE macro removes an element from an array.

Usage

BOOST_PP_ARRAY_REMOVE(array, i)

Arguments

  • array : The array from which an element is to be removed.

  • i : The zero-based position in array of the element to be removed. Valid values range from 0 to BOOST_PP_ARRAY_SIZE(array) - 1.

Remarks

This macro uses BOOST_PP_WHILE interally. Therefore, to use the d parameter passed from other macros that use BOOST_PP_WHILE, see BOOST_PP_ARRAY_REMOVE_D.
