Bug ID: 78075
Summary: Need a way to tell pthread_cancel don't to the forced
unwind
Product: gcc
Version: 4.5.2
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: baiyang at gmail dot com
Target Milestone: ---
I want pthread_cancel not throw __forced_unwind exception, and there is no need
to do the cleanup in our case. e.g.: I just want terminate the thread
immediately without ANY cleanup, like the TerminateThread Win32 API.
As far as I known, behaviors of the musl-libc and CLang libc are both equal to
the TerminateThread API.
I understand __forced_unwind is very useful in some cases, but it is clearly
unable to adapt to all situations.
So could we add a new API, let user set the wanted behavior of pthread_cancel,
like: pthread_setcancelmethod(PTHREAD_CANCEL_NO_UNWIND) ?
