const PTHREAD_MUTEX_NORMAL_FLAG: i32 = 0x8000000;Expand description
A flag that allows to distinguish PTHREAD_MUTEX_NORMAL from
PTHREAD_MUTEX_DEFAULT. Since in glibc they have the same numeric values,
but different behaviour, we need a way to distinguish them. We do this by
setting this bit flag to the PTHREAD_MUTEX_NORMAL mutexes. See the comment
in pthread_mutexattr_settype function.
