/** Delays the stringization of X.
|
|
|
|
For example,
|
|
|
|
<PRE>\verbatim
|
|
#define NOTE(STR)\
|
|
message(__FILE__ "(" BOOST_PP_STRINGIZE(__LINE__) ") : " STR)
|
|
|
|
// ...
|
|
|
|
#pragma NOTE("TBD!")
|
|
\endverbatim</PRE>
|
|
|
|
expands to:
|
|
|
|
<PRE>\verbatim
|
|
#pragma message("examples.cpp" "(" "20" ") : " "TBD!")
|
|
\endverbatim</PRE>
|
|
|
|
The use of BOOST_PP_STRINGIZE() above lets the PP 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>
