BOOST_PP_ENUM_BINARY_PARAMS_Z

Boost , ,

Usage

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.

p1

The text of the first part of the parameter.  BOOST_PP_ENUM_BINARY_PARAMS concatenates numbers ranging from 0 to count - 1 to generate parameters.

p2

The text of the first part of the parameter.  BOOST_PP_ENUM_BINARY_PARAMS concatenates numbers ranging from 0 to count - 1 to generate parameters.
