//! Delays the stringization of E.

Example:
|
|
|
|
|
|
|
|
|
|
<PRE>\verbatim
|
|
|
|
|
#define NOTE(STR)\
|
|
|
|
|
message(__FILE__ "(" BOOST_PREPROCESSOR_STRINGIZE(__LINE__) ") : " STR)
|
|
|
|
|
|
|
|
|
|
// ...
|
|
|
|
|
|
|
|
|
|
#pragma NOTE("TBD!")
|
|
|
|
|
\endverbatim</PRE>
|
|
|
|
|
|
|
|
|
|
The above expands to:
|
|
|
|
|
|
|
|
|
|
<PRE>\verbatim
|
|
|
|
|
#pragma message("examples.cpp" "(" "20" ") : " "TBD!")
|
|
|
|
|
\endverbatim</PRE>
|
|
|
|
|
|
|
|
|
|
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:
|
|
|
|
|
|
|
|
|
|
<PRE>\verbatim
|
|
|
|
|
#pragma message("examples.cpp" "(" "__LINE__" ") : " "TBD!")
|
|
|
|
|
\endverbatim</PRE>
|
|
|
