poll_in函数是基于poll系统调用的,它能够同时监测多个文件描述符的可读状态。相比于传统的select函数,poll函数的效率更高,可以处理更多的文件描述符。在使用poll_in函数之前,需要先创建一个poll对象,并将需要监测的文件描述符注册到poll对象中。 poll_in函数的使用非常简单,只需要传入一个文件描述符和一个可选的超时...
int poll(struct pollfd *fdarray, unsigned long nfds, int timeout); 返回:就绪描述字的个数,0-超时,-1-出错 第一个参数是指向一个结构数组第一个元素的指针。每个数组元素都是一个pollfd结构,用于指定测试某个给定描述字fd的条件。 struct pollfd{ int fd; //descriptor to check short events; //eve...

Linux poll in 是一个 Linux 系统中的系统调用函数,用于监听特定的文件描述符的输入事件。在 Linux 内核中,每个进程都有一个打开文件描述符表,通过 poll in 函数,可以检查这些文件描述符上是否有可读、可写或错误事件发生。 poll in 函数的语法如下:
With uart_poll_in (or interrupts) I am not able to read the message. To Reproduce void send_str(const struct device *uart, char *str) { int msg_len = strlen(str); for (int i = 0; i < msg_len; i++) { uart_poll_out(uart, str[i]); } // printk("Device %s sent: \"...

Remove the UV__POLL defines and use POLL{IN,OUT,etc} directly. On Linux, we lean on the fact that the POLL constants correspond one-to-one with their EPOLL counterparts. Fixes: #816 CI: https://ci.nodejs.org/job/libuv-test-commit/21/ bnoordhuis mentioned this pull request Apr 9, ...
