Abstract
User code is operated in either a multithreaded or non-threaded programming environment by linking the code to different libraries. A standard thread library is linked with the code when operated in a multithreaded mode. A null thread library is linked to the code to operate in a non-threaded mode. The different libraries are linked to the user code through a common application programming interface allowing the same thread function calls to operate in either the multithreaded or non-threaded mode. The null thread library implements thread function calls as blocking functions which synchronize thread launches while eliminating the performance and memory overhead required in multithreaded processes.
