msvc veya alternatif bir geçici çözüm için __typeof__ öykünmenin en iyi yolu?

bir değişken ya da bir ifade de olabilir DEBUG_PRINT içinde x bir işaretçi mi var. İfadeleri desteklemek için onu geçici olarak atarım ve sonra bunun adresini alırım. 'u _Generic ile sınırlı bir tür kümesi için taklit edebilirdim, ancak kullanıcıların 2 yerde özel türler için çizgiler eklemesi gerekir. Bunu yapmanın başka bir yolu var mı? En yeni Microsoft C derleyicisini destekleyerek tamam olurdum.

char: debug_print_printf_specifier("x"//z.str, (void *)xp, \ 
TYPE_PTR_TO_PRINTF_SPECIFIER(xp), __FILE__, __LINE__, _my_func__, \ 
debug_print_options_apply_group_options(&((debug_print_options{__VA_ARGS__}))),\ 
z=ptr.x 
//just create a ptr z for x... :D 

bu kadar basit ..;)
