Macro function and preprocessed file

[serkan sendur]

i tried to see the preprocessed file after it is preprocessed.

i created den.cpp :

#define PROC_ERR(MSGSTR, DO_ACTION) \
   { \
      cerr << MSGSTR << endl; \
      DO_ACTION; \
   }

PROC_ERR(error,action)

i run the following command on unix command prompt to create the preprocessed file :

g++ -E -o den.i den.cpp

the content of the preprocessed file "den.i" is as follows

# 1 "den.cpp"
# 1 "<built-in>"
# 1 "<command line>"
# 1 "den.cpp"

{ cerr << error << endl; action; }
