Function Documentation

◆ AuPoll()

int AuPoll	(	_AuUser_PollFD	fds[],
		nfds_t	num_fd,
		int	timeout
	)

extern

AuPoll – poll system call.

Parameters

fds	– Pointer to file descriptor array
num_fd	– number of file descriptor to monitor
timeout	– timeout in millisecond

copy it from user

check all file descriptors

the poll system call suggest that it revent should have POLLERR | POLLHUP | POLLNVAL present

check for timeout value , 0 means non-blocking and non sleeping, -1 means forever

we should also check for signal, but skipping for now

◆ AuPollWait()

AU_EXTERN AU_EXPORT void AuPollWait	(	AuWaitQueue *	q,
		AuPollTable *	pt
	)

AuPollWait – helper function to create a wait queue.
