The BOOST_PP_ENUM_SHIFTED_PARAMS_Z macro generates a comma-separated, shifted list of parameters.  It reenters BOOST_PP_REPEAT with maximum efficiency.

Usage

BOOST_PP_ENUM_SHIFTED_PARAMS_Z(z, count, param)

Arguments

z
The next available BOOST_PP_REPEAT dimension.
count
The number of parameters to generate.  Valid values range from 0 to BOOST_PP_LIMIT_REPEAT.
param
The text of the parameter.  BOOST_PP_ENUM_SHIFTED_PARAMS_Z concatenates numbers ranging from 1 to count - 1 to generate parameters.

Remarks

This macro expands to the comma-separated sequence:
param ## 1, ... param ## count - 1
