The BOOST_PP_RELATIVE_START macro expands to the lower bound of a file-iteration depth relative to the current depth.

Usage

BOOST_PP_RELATIVE_START(i)

Arguments

i
The relative depth of the frame whose lower bound is to be retreived.  Valid values range from 0 to BOOST_PP_ITERATION_DEPTH() - 1.

Remarks

This macro is only valid when a file-iteration is in progress.
The argument i is interpreted as the number of frames outward from the current frame.
