BOOST_PP_ENUM_TRAILING_PARAMS_Z

The BOOST_PP_ENUM_TRAILING_PARAMS_Z macro generates a comma-separated list of parameters with a leading comma. It reenters BOOST_PP_REPEAT with maximum efficiency.

#### Usage

BOOST_PP_ENUM_TRAILING_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_TRAILING_PARAMS_Z 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
