5 Programming with Kernel

Threads

Programming with threads is useful for structuring programs,

performance enhancement through concurrency and overlapping I/O,

and making client/server interaction more efﬁcient (it increases

programming complexity). Some things that need to be addressed when

programming with threads are:

• Creation and management of threads.

• Threads synchronization and communication.

• Threads scheduling.

• Error handling

A traditional non-threaded process has a single thread of control,

started and terminated with the process. Multi-threaded programs

require that threads be created and terminated explicitly.

The HP e3000 Kernel Threads provide basic thread creation and

management routines.
