Hi Dear, I just wanna to know my processor architecture(32bit or 64 bit) through c programming. According to me the sizeof of pointer will give the result. Like below coding. int main() { int *ptr; printf("%d",sizeof(ptr)); } Please correct me if i am wrong... Any suggestion or help would be appreciated. Thanks, Prabhu _______________________________________________ Kernelnewbies mailing list Kernelnewbies@xxxxxxxxxxxxxxxxx http://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
