Is it possible to call function-like-macros with less that all the parameters in linux?
Actually doing this only generates a warning in Visual Studio (warning 4003) and unassigned variables replaces with “”.
But compiling it using g++ generates an error in linux (“error: macro *** requires ** arguments, but only ** given”).
Is there any possible way to disable this or overcome it?
The number of arguments in a macro invocation must exactly match the number of parameters in the macro definition. So, no, you cannot invoke a macro with fewer arguments than it has parameters.
To “overcome” it, you can define multiple differently named macros with different numbers of parameters.
C++0x (which is not yet standard, but which your compiler might partially support) adds support for variadic macros which can be called with a variable number of arguments.
