Replace the mock login with:
int psn_get_friends(PsnFriend *friends, int max_friends) !friends) return -1; // Mock friends PsnFriend mock_friends[] = "111", "Alice", 1, "222", "Bob", 0, "333", "Charlie", 1 ; int count = (max_friends < 3) ? max_friends : 3; memcpy(friends, mock_friends, count * sizeof(PsnFriend)); return count; 4.7 Trophy Sync Stub int psn_sync_trophies(void) if (!psn_is_session_valid()) return -1; printf("[PSN] Syncing trophies with server... (stub)\n"); return 0; // success
Always check return values:
if (psn_login("user@example.com", "pass") != 0) fprintf(stderr, "Login failed\n"); return; psnuser.c
Then implement psn_login to POST to a local test server. Unit test snippet (using assert) void test_login_logout() psn_init(); assert(psn_login("a@b.com", "1234") == 0); assert(psn_is_session_valid() == 1); psn_logout(); assert(psn_is_session_valid() == 0); psn_shutdown();
