|
|
* The thread subsystem is responsible for all thread functions. It
|
|
* provides a thread implementation agnostic interface to Iperf. If
|
|
* threads are not available (HAVE_THREAD is undefined), thread_start
|
|
* does not start a new thread but just launches the specified object
|
|
* in the current thread. Everything that defines a thread of
|
|
* execution in Iperf is contained in an thread_Settings structure. To
|
|
* start a thread simply pass one such structure into thread_start.
