I tried to get this code working with Active State 5.20, but I don't have right "formula" to do that on my current little laptop. Is there a FAQ on this? What compiler is necessary, etc...?
PS: I think your check() would be more "C like" coded something like this:
void check(unsigned char* n, int len)
printf ("%d\n", *n++);
The variable: int i is unnecessary. With the C calling
convention on 32 bit machine, check() is passed a 32 bit pointer to n (pointer to an array of unsigned bytes) and a 32 bit signed integer, len on the stack. These are copies for the subroutine to modify and use as it wishes.
This n[i] syntax is often coded by the compiler as (
n i*size_of_n) plus base address. Whereas n++ is coded as n plus the size_of_n.
