-/* Like many systems, UnixWare implements two classes of threads:
- kernel-mode threads, which are scheduled by the kernel; and
- user-mode threads, which are scheduled by a library. UnixWare
- calls these two classes lightweight processes (LWPs) and threads,
- respectively.
-
- This module deals with user-mode threads. It calls procfs_ops
- functions to deal with LWPs and processes and core_ops functions to
- deal with core files.
-
- As of this writing, the user-mode thread debugging interface is not
- documented beyond the comments in <thread.h>. The following
- description has been gleaned from experience and from information
- provided by SCO.
-
- libthread.so, against which all UnixWare user-mode thread programs
- link, provides a global thread_debug structure named _thr_debug.
- It has three fields:
-
- (1) thr_map is a pointer to a pointer to an element of a
- thread_map ring. A thread_map contains a single thread's id
- number, state, LWP pointer, recent register state, and other
- useful information.
-
- (2) thr_brk is a pointer to a stub function that libthread.so
- calls when it changes a thread's state, e.g. by creating it,
- switching it to an LWP, or causing it to exit.
-
- (3) thr_debug_on controls whether libthread.so calls thr_brk().
-
- Debuggers are able to track thread activity by setting a private
- breakpoint on thr_brk() and setting thr_debug_on to 1.
-
- thr_brk() receives two arguments:
-
- (1) a pointer to a thread_map describing the thread being
- changed; and
-
- (2) an enum thread_change specifying one of the following
- changes:
-
- invalid unknown
- thread_create thread has just been created
- thread_exit thread has just exited
- switch_begin thread will be switched to an LWP
- switch_complete thread has been switched to an LWP
- cancel_complete thread wasn't switched to an LWP
- thread_suspend thread has been thr_suspend()ed
- thread_suspend_pending thread will be thr_suspend()ed
- thread_continue thread has been thr_continue()d
-
- The thread_map argument to thr_brk() is NULL under the following
- circumstances:
-
- - The main thread is being acted upon. The main thread always
- has id 1, so its thread_map is easy to find by scanning through
- _thr_debug.thr_map.
-
- - A "switch_complete" change is occurring, which means that the
- thread specified in the most recent "switch_begin" change has
- moved to an LWP.
-
- - A "cancel_complete" change is occurring, which means that the
- thread specified in the most recent "switch_begin" change has
- not moved to an LWP after all.
-
- - A spurious "switch_begin" change is occurring after a
- "thread_exit" change.
-
- Between switch_begin and switch_complete or cancel_complete, the
- affected thread's LWP pointer is not reliable. It is possible that
- other parts of the thread's thread_map are also unreliable during
- that time. */
