Hi! > On 32bit char pointer is int and size_t is unsigned int, > Cast to long / unsigned long. Actually char pointer is char pointer, that is not an integer type at all. If you do a pointer difference you end up with an signed integer value of ptrdiff_t type, because unlike the result of sizeof(foo) pointer difference can be negative as well. In C99 ptrdiff_t can be printed as %td see the "Length modifier" part of man 3 printf. -- Cyril Hrubis chrubis@xxxxxxx
