casting char* to char**
- by blue_whale
I am having a tough time understanding the following piece of code:
int stride = 512;
int max_len = 1024 * stride;
char *addr = (char *)malloc(max_len);
for (int i=stride; i<max_len; i += stride)
*(char **)&addr[i-stride] = (char*)&addr[i];
*(char **)&addr[i-stride] = (char*)&addr[0];
Looking at the code it seems this is trying to create some kind of circular link list. But I have no clue what those casts are actually doing.
