BOOST_PP_ITERATION_FLAGS

The BOOST_PP_ITERATION_FLAGS macro retrieves flags associated with the current file-iteration depth.

#### Usage

BOOST_PP_ITERATION_FLAGS()

#### Remarks

This macro is only valid when a file-iteration is in progress.

#### Requirements

Header: <boost/preprocessor/iteration/iterate.hpp>

#### Sample Code

    // file.h
    #if !BOOST_PP_IS_ITERATING

       #ifndef FILE_H_
       #define FILE_H_

       #include <boost/preprocessor/iteration/iterate.hpp>

       // 1st iteration:
       #define BOOST_PP_ITERATION_PARAMS_1 (4, (1, 10, "file.h", 0x0001))
       #include BOOST_PP_ITERATE()

       // 2nd iteration:
       #define BOOST_PP_ITERATION_PARAMS_1 (4, (1, 10, "file.h", 0x0002))
       #include BOOST_PP_ITERATE()

       #endif

    #elif BOOST_PP_ITERATION_DEPTH() == 1 \
       && BOOST_PP_ITERATION_FLAGS() == 0x0001 \
       /**/

       { 1st }

    #elif BOOST_PP_ITERATION_DEPTH() == 1 \
       && BOOST_PP_ITERATION_FLAGS() == 0x0002 \
       /**/

       { 2nd }

    #endif
