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.
