Problem - Kevin Tafuro

Upon receipt of a response to a confirmation request, the address from which it was
sent and the unique identified contained within it should be passed as arguments to
spc_confirmation_receive( ) (SpcConfirmationReceive() on Windows). If the address
and unique identifier are in the list of pending requests, the return from this function
will be 1; otherwise, it will be 0. Before the list is checked, expired entries will
automatically be removed.
int spc_confirmation_receive(const char *address, const char *id) {
time_t now;
unsigned long i;
/* Before we check the pending list of confirmations, prune the list to
* remove expired entries.
*/
now = time(0);
for (i = 0; i < confirmation_count; i++) {
if (confirmations[i].expire 1 && i < confirmation_count - 1)
confirmations[i] = confirmations[confirmation_count - 1];
i--;
confirmation_count--;
}
}
for (i = 0; i < confirmation_count; i++) {
if (!strcmp(confirmations[i].address, address)) {
if (strcmp(confirmations[i].id, id) != 0) return 0;
free(confirmations[i].address);
free(confirmations[i].id);
if (confirmation_count > 1 && i < confirmation_count - 1)
confirmations[i] = confirmations[confirmation_count - 1];
confirmation_count--;
return 1;
}
}
return 0;
}
The Windows versions of spc_confirmation_create( ) and spc_confirmation_
receive( ) are named SpcConfirmationCreate( ) and SpcConfirmationReceive( ),
respectively. The arguments and return values for each are the same; however, there
are enough subtle differences in the underlying implementation that we present an
entirely separate code listing for Windows instead of using the preprocessor to have
a single version.
