# #include <boost/preprocessor/repeat.hpp>

## #define BOOST_PP_REPEAT(COUNT,MACRO,DATA)

Repeats the macro `MACRO(INDEX,DATA)` for `INDEX = [0,COUNT)`.

In other words, expands to the sequence:

      MACRO(0,DATA) MACRO(1,DATA) ... MACRO(BOOST_PP_DEC(COUNT),DATA)

For example,

      #define TEST(INDEX,DATA) DATA(INDEX);
      BOOST_PP_REPEAT(3,TEST,X)

expands to:

      X(0); X(1); X(2);

### 2D and 3D repetition

2D and 3D repetition are supported with the BOOST_PP_REPEAT_2ND() and BOOST_PP_REPEAT_3RD() macros.

### Example

- duffs_device.c
- repeat_2d.c

### See

- BOOST_PP_FOR()
- BOOST_PP_LIMIT_MAG
