Is it possible to call macro functions in Simulink?

Dear all,

Is it possible to call macro functions defined in C header files in Simulink?

For instanceand for the sake of argument, you have the following header file (errPro.h) :

#ifndef ERRPRO_H_
#define ERRPRO_H_

#define MAXi(a, b) (((a)>(b))?(a):(b))
#define xyz(a, b) ((a)<(b))
#endif

After including this particular header file to the right place (Simulation Target -> Header File), is it possible to call these macro functions in Simulink? I know that it is possible to call functions with c caller in Simulink, but I was not able to figure it out with macro functions.

Any help is highly appriciated, so thanks in advance.

Best regards,

Szabi
