Compiler Warning (level 1, Error) C4003

not enough arguments for function-like macro invocation 'identifier'

Remarks

The number of formal parameters in the macro definition exceeds the number of actual parameters in the macro. Macro expansion substitutes empty text for the missing parameters.

Example

The following example generates C4003:

// C4003.cpp
// compile with: /WX
#define test(a,b) (a+b)

int main()
{
   int a = 1;
   int b = 2;
   a = test(b);   // C4003
   // try..
   a = test(a,b);
}
