sockets, so this also wastes some overhead.PollPoll was born in 1986 in System V Release 3, and it does not differ substantially from select in nature, but poll does not have a limit on the maximum number of file descriptors .The disadvantage of poll and select is that an array containing a large number of file descriptors is copied in between the user state and the kernel's address space, regardless of wh

The poll system call is similar to select and polls a certain number of file descriptors within a specified time to test if there is a ready person. Poll and select efficiency is similar, but its use of the interface is relatively simple, poll is not limited to 1024 file descriptors, poll listener events and trigger ev

collection of abnormal descriptive words of interest, that is, when a descriptive word in the collection encounters an exception, it will receive a notification from the kernel. Timeout Used to specify the timeout length. This is a struct.

For objective reasons, the new developments in Linux have failed to keep up with the new development of the Linux kernel, especially in the ever-changing Linux kernel. This article explains the main differences between select/poll in UNIX and epoll in Linux. 1. support a process to open a large number of socket Descriptors (FD) The most intolerable thing about select isThe FD opened by a process has certain limitations.,Fd_setsizeSet, the default

Poll is similar to select, which iterates through the descriptor to see if a descriptor is ready. Returns the number of ready file descriptors if one is available. The poll function is as follows:#include int poll (struct POLLFD *fdarray, unsigned long nfds, int timeout)The first argument points to a pointer to the first element of the structure array, each of wh

immediately gets a result. When the user process determines that the result is an error, it knows that the data is not ready, so it can send the read operation again. Once the data in the kernel is ready and again receives the system call of the user process, it immediately copies the data to the user's memory and then returns. Therefore, nonblocking IO is characterized by the user process needs to constantly proactively ask kernel data well no. I/O multiplexing (IO multiplexing) IO multiplexin

The poll function is similar to the SELECT functionFunction Prototypes:#include int poll (structint timeout);struct POLLFD is structured as follows:struct pollfd{ int// file descriptor short event;// requested event short revent;// event returned }　　Each pollfd struct specifies a monitored file descriptor.
