## Define Documentation

#define BOOST_PREPROCESSOR_STRINGIZE | ( | E |  | ) |

Delays the stringization of E.

Example:

    #define NOTE(STR)\
      message(__FILE__ "(" BOOST_PREPROCESSOR_STRINGIZE(__LINE__) ") : " STR)

    // ...

    #pragma NOTE("TBD!")

The above expands to:

      #pragma message("examples.cpp" "(" "20" ") : " "TBD!")

The use of BOOST_PREPROCESSOR_STRINGIZE() above lets the preprocessor expand the __LINE__ before stringizing it. If # would be used directly, the code would expand to:

      #pragma message("examples.cpp" "(" "__LINE__" ") : " "TBD!")
