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.
