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!")
