C++ (Cpp) user_mutex_lock Examples

Example #1

File: user_mutex.cpp Project: SummerSnail2014/haiku

status_t
_user_mutex_lock(int32* mutex, const char* name, uint32 flags,
	bigtime_t timeout)
{
	if (mutex == NULL || !IS_USER_ADDRESS(mutex) || (addr_t)mutex % 4 != 0)
		return B_BAD_ADDRESS;

	syscall_restart_handle_timeout_pre(flags, timeout);

	status_t error = user_mutex_lock(mutex, name, flags | B_CAN_INTERRUPT,
		timeout);

	return syscall_restart_handle_timeout_post(error, timeout);
}
