#define IAP_LOCATION 0x7ffffff1
...
unsigned long command[5];
unsigned long result[3];
...
typedef void (*IAP)(unsigned int [],unsigned int[]);
IAP iap_entry;

iap_entry = (IAP) IAP_LOCATION;

iap_entry(command, result);

Can someone explain how it works, especially below code

iap_entry = (IAP) IAP_LOCATION;
iap_entry(command, result)

It is calling a function at a specific address. Look up "function pointers" in the C language.
