Boost.Preprocessor

#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

BOOST_PP_REPEAT() implements automatic recursion. 2D and 3D repetition are directly supported.

Example

• duffs_device.c
• repeat_2d.c

See

• BOOST_PP_FOR()
• BOOST_PP_LIMIT_DIM
• BOOST_PP_LIMIT_MAG

Test

• repeat_test.cpp
• repeat_2nd_test.cpp

#define BOOST_PP_REPEAT_2ND

Obsolete, just use BOOST_PP_REPEAT().

#define BOOST_PP_REPEAT_3RD

Obsolete, just use BOOST_PP_REPEAT().
