Definition in file rte_epoll.h. Macro Definition Documentation #define RTE_EPOLL_PER_THREAD -1 to hint using per thread epfd Definition at line 48 of file rte_epoll.h. Function Documentation int rte_epoll_wait (int epfd, struct rte_epoll_event * events, int maxevents, int timeout) It waits for events on the epoll instance. Retries if signal received. Parameters epfd Epoll instance fd on which the caller wait for events. events Memory area contains the events that will be available for the caller. maxevents Up to maxevents are returned, must greater than zero. timeout Specifying a timeout of -1 causes a block indefinitely. Speci- fying a timeout equal to zero cause to return immediately. Returns * On success, returns the number of available event. * On failure, a negative value. int rte_epoll_wait_interruptible (int epfd, struct rte_epoll_event * events, int maxevents, int timeout) It waits for events on the epoll instance. Does not retry if signal re- ceived. Parameters epfd Epoll instance fd on which the caller wait for events. events Memory area contains the events that will be available for the caller. maxevents Up to maxevents are returned, must greater than zero. timeout Specifying a timeout of -1 causes a block indefinitely. Speci- fying a timeout equal to zero cause to return immediately. Returns * On success, returns the number of available event. * On failure, a negative value. int rte_epoll_ctl (int epfd, int op, int fd, struct rte_epoll_event * event) It performs control operations on epoll instance referred by the epfd. It requests that the operation op be performed for the target fd. Parameters epfd Epoll instance fd on which the caller perform control operations. op The operation be performed for the target fd. fd The target fd on which the control ops perform. event Describes the object linked to the fd. Note: The caller must take care the object deletion after CTL_DEL. Returns * On success, zero. * On failure, a negative value. Author Generated automatically by Doxygen for DPDK from the source code.
