|
| -** API for NSPR threads. On some architectures (MAC and WIN16
|
| -** notably) pre-emptibility is not guaranteed. Hard priority scheduling
|
| -** is not guaranteed, so programming using priority based synchronization
|
| -** is a no-no.
|
| -**
|
| -** NSPR threads are scheduled based loosly on their client set priority.
|
| -** In general, a thread of a higher priority has a statistically better
|
| -** chance of running relative to threads of lower priority. However,
|
| -** NSPR uses multiple strategies to provide execution vehicles for thread
|
| -** abstraction of various host platforms. As it turns out, there is little
|
| -** NSPR can do to affect the scheduling attributes of "GLOBAL" threads.
|
| -** However, a semblance of GLOBAL threads is used to implement "LOCAL"
|
| -** threads. An arbitrary number of such LOCAL threads can be assigned to
|
| -** a single GLOBAL thread.
|
| -**
|
| -** For scheduling, NSPR will attempt to run the highest priority LOCAL
|
| -** thread associated with a given GLOBAL thread. It is further assumed
|
| -** that the host OS will apply some form of "fair" scheduling on the
|
| -** GLOBAL threads.
|
| -**
|
| -** Threads have a "system flag" which when set indicates the thread
|
| -** doesn't count for determining when the process should exit (the
|
| -** process exits when the last user thread exits).
|
| -**
|
| -** Threads also have a "scope flag" which controls whether the threads
|
| -** are scheduled in the local scope or scheduled by the OS globally. This
|
| -** indicates whether a thread is permanently bound to a native OS thread.
|
| -** An unbound thread competes for scheduling resources in the same process.
|
| -**
|
| -** Another flag is "state flag" which control whether the thread is joinable.
|
| -** It allows other threads to wait for the created thread to reach completion.
|
| -**
|
| -** Threads can have "per-thread-data" attached to them. Each thread has a
|
| -** per-thread error number and error string which are updated when NSPR
|
| -** operations fail.
