Subject: [PATCH] Fix invalid sigprocmask call
|
|
|
|
The POSIX document says
|
|
|
|
The pthread_sigmask() and sigprocmask() functions shall fail if:
|
|
|
|
[EINVAL]
|
|
The value of the how argument is not equal to one of the defined values.
|
|
|
|
and this is how musl-libc is currently doing. Fix the call to be safe
|
|
and correct
|
|
