Subject: [PATCH] profile-handler: use documented sigev_notify_thread_id in
|
|
sigevent
|
|
|
|
sigevent(7) is documented to have sigev_notify_thread_id as its member.
|
|
In glibc system, it's a macro expanded to the legacy _sigev_un._tid,
|
|
_sigev_un._tid is obviously an internal implementation detail as
|
|
signaled by its underscore prefix. And this macro was hidden inside
|
|
linux/signal.h in older version of glibc.
|
|
|
|
On Linux that use musl libc, sigev_notify_thread_id is also a macro, but
|
|
it's expanded to __sev_fields.sigev_notify_thread_id
|
|
|
