LIBPTHREAD
This is the pthread implementation of dietlibc.
Written from scratch by Olaf Dreesen.
1. STATUS: incomplete but should work (or not... I had a lot of heisen-bugs...)
On non i386 archs the kernel header have major differences...
NO workaround yet for this problems...
It's like linuxthreads a clone base thread implementation.
I have implemented a "Manager Thread" with all the pain it involves...
Nested thread creation is now working fine...
2. HOW-TO make this lib:
1. generate the dietlibc in the parent directory.
and make sure you have WANT_THREAD_SAVE active in the file:
dietfeatures.h
2. change back here and type make
and then you should have a libpthread.a
3. NOTES
NON STANDARD SIGNAL HANDLING for the threads:
SIGHUP the targeted thread is canceled
depends on the cancel type of the thread.
ASYNCHRONOUS: the signal handler will KILL the thread immediately.
DEFERRED: the signal handler mark its thread as canceled.
(only for the sig-handler to do some sane stuff...)
SIGTERM the thread is KILLED
if the thread signaled is the main thread, then ALL child-threads
will get a SIGHUP and after some micros a SIGTERM....
