Ahojte, chcem si spravit makro na podmieneny vypis takto:

Kód:

#define PRINT(...) \
   #ifdef DEBUG_OUTPUT\
   DbgPrint(__VA_ARGS__);\
   #endif

ale bohuzial to nefunguje a vypisuje tieto errory:

Kód:

1>c:\users\administrator\desktop\work\testing\driver\driver.c(536) : error C2065: 'endif' : undeclared identifier
1>c:\users\administrator\desktop\work\testing\driver\driver.c(546) : error C2065: 'ifdef' : undeclared identifier
1>c:\users\administrator\desktop\work\testing\driver\driver.c(546) : error C2146: syntax error : missing ';' before identifier 'DbgPrint'
1>c:\users\administrator\desktop\work\testing\driver\driver.c(546) : error C2065: 'endif' : undeclared identifier
1>c:\users\administrator\desktop\work\testing\driver\driver.c(553) : error C2065: 'ifdef' : undeclared identifier
1>c:\users\administrator\desktop\work\testing\driver\driver.c(553) : error C2146: syntax error : missing ';' before identifier 'DbgPrint'
1>c:\users\administrator\desktop\work\testing\driver\driver.c(553) : error C2065: 'endif' : undeclared identifier
1>c:\users\administrator\desktop\work\testing\driver\driver.c(602) : error C2065: 'ifdef' : undeclared identifier

Skusal som aj '\' pred '#' ale konci to s illegal escape sequence. Nejake napady?

Take nieco sa neda, musis to rozdelit:

Kód:

#ifdef DEBUG_OUTPUT
    #define PRINT(...) \
        DbgPrint(__VA_ARGS__);
#else
    #define PRINT(...) \
        printf( "nieco ine" );
#endif
