I experienced problems as not using parenthesis with addressing operator.
Does someone know what's correct?
pthread_mutex_lock.c
int e = INTERNAL_SYSCALL (futex, __err, 4,
&mutex->__data.__lock,
__lll_private_flag (FUTEX_LOCK_PI,
private), 1, 0);
ags_thread-posix.c
pthread_mutex_init(&(thread->timelock_mutex), NULL);
They are both the same.
The -> and . have precedence over & with left-to-right associativity.
Therefore &(struct->member) is equivalent to &struct->member.
Only () can change this e.g. *(ptr[x]) is not equivalent (*ptr)[x].
