BOOST_PP_ENUM_TRAILING_BINARY_PARAMS

The BOOST_PP_ENUM_TRAILING_BINARY_PARAMS macro generates a comma-separated list of binary parameters with a leading comma.

Usage

BOOST_PP_ENUM_TRAILING_BINARY_PARAMS (count, p1, p2)

Arguments

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_TRAILING_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_TRAILING_BINARY_PARAMS concatenates numbers ranging from 0 to count - 1 to generate parameters.

Remarks

This macro expands to the comma-separated sequence: , p1 ## 0 p2 ## 0, p1 ## 1 p2 ## 1, ... p1 ## count - 1 p2 ## count - 1

To use the z parameter passed from other macros that use BOOST_PP_REPEAT , see BOOST_PP_ENUM_TRAILING_BINARY_PARAMS_Z.
