The BOOST_PP_ARRAY_REPLACE macro replaces an element in an array.

Usage

BOOST_PP_ARRAY_REPLACE(array, i, elem)

Arguments

array
An array to replace an element in.
i
The zero-based position in array of the element to be replaced.  Valid values range from 0 to BOOST_PP_ARRAY_SIZE(array) - 1.
elem
The replacement element.

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_REPLACE_D.
