HDLL = LoadLibrary ("D: // Guangdong Construction Bank //sleep/sleep//debug//sleep.dll" ); // load dynamic link library Sleep.dll file; psleep = (psleep) getProcaddress (HDLL, "Sleep"); for (int i = 0; i <3; i ) {printf ("Sleeping for% D Seconds / N", I); PSLEEP (300);} Freelibrary (HDLL); // Uninstall MyDLL.
