The BOOST_PP_REPEAT_3RD macro represents the third dimension of BOOST_PP_REPEAT.

Usage

BOOST_PP_REPEAT_3RD(count, macro, data)

Arguments

count
The number of repetitious calls to macro.  Valid values range from 0 to BOOST_PP_LIMIT_REPEAT.
macro
A ternary operation of the form macro(z, n, data).  This macro is expanded by BOOST_PP_REPEAT_3RD with the next available repetition depth, the current repetition number, and the auxiliary data argument. 
data
Auxiliary data passed to macro.

Remarks

This macro expands to the sequence:
macro(z, 0, data) macro(z, 1, data) ... macro(z, count - 1, data)
The z value that is passed to macro represents the next available repetition dimension.  Other macros that have _Z suffix variants internally use BOOST_PP_REPEAT--for example, BOOST_PP_ENUM_PARAMS and BOOST_PP_ENUM_PARAMS_Z.  Using these _Z versions is not strictly necessary, but passing the z value (that is passed to macro) to these macros allows them to reenter BOOST_PP_REPEAT with maximum efficiency.
To directly use this z value, rather than simply passing it to another macro, see BOOST_PP_REPEAT_z.
This macro is deprecated.  It only exists for backward compatibility.  Use BOOST_PP_REPEAT instead.
