v01d opened a new issue #3327:
URL: https://github.com/apache/incubator-nuttx/issues/3327
```
Description: When a tasks exits, shouldn't all of its child pthreads also
be
terminated?
This behavior was implemented as an options controlled by the
configuration setting CONFIG_SCHED_EXIT_KILL_CHILDREN. This
option must be used with caution, however. It should not be
used unless you are certain of what you are doing. Uninformed
of this option can often lead to memory leaks since, for
example, memory allocations held by threads are not
automatically freed!
Status: Closed. No, this behavior will not be implemented unless
specifically selected.
Priority: Medium, required for good emulation of process/pthread model.
The current behavior allows for the main thread of a task to
exit() and any child pthreads will persist. That does raise
some issues: The main thread is treated much like
just-another-
pthread but must follow the semantics of a task or a process.
That results in some inconsistencies (for example, with robust
mutexes, what should happen if the main thread exits while
holding a mutex?)
