The BOOST_PP_ENUM_PARAMS macro generates a comma-separated list of parameters.

Usage

BOOST_PP_ENUM_PARAMS(count, param)

Arguments

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

Remarks

This macro expands to the comma-separated sequence:
param ## 0, param ## 1, ... param ## count - 1
To use the z parameter passed from other macros that use BOOST_PP_REPEAT, see BOOST_PP_ENUM_PARAMS_Z.
Previously, this macro could not be used recursively inside BOOST_PP_REPEAT.  This limitation no longer exists, as the library can automatically detect the next available repetition depth.
