The solution to too many macros is always MOAR MACROS! This is valid: PETSC_EXTERN PetscErrorCode PetscFunctionListAdd(PetscFunctionList*,const char[],void (*)(void)); #define PetscFunctionListAdd(list,name,fptr) PetscFunctionListAdd((list),(name),(PetscVoidFunction)(fptr)) off in the implementation: #undef PetscFunctionListAdd PETSC_EXTERN PetscErrorCode PetscFunctionListAdd(PetscFunctionList *fl,const char name[],void (*fnc)(void)) { ... } This would make the debugging thing work, at the expense of being slightly more confusing to the reader. But maybe comments would be enough to explain what's going on?
