 sun.nio.ch.EPollArrayWrapper
| EPollArrayWrapper | | class EPollArrayWrapper (Code) | | Manipulates a native array of epoll_event structs on Linux:
typedef union epoll_data {
void *ptr;
int fd;
__uint32_t u32;
__uint64_t u64;
} epoll_data_t;
struct epoll_event {
__uint32_t events;
epoll_data_t data;
};
The system call to wait for I/O events is epoll_wait(2). It populates an
array of epoll_event structures that are passed to the call. The data
member of the epoll_event structure contains the same data as was set
when the file descriptor was registered to epoll via epoll_ctl(2). In
this implementation we set data.fd to be the file descriptor that we
register. That way, we have the file descriptor available when we
process the events.
All file descriptors registered with epoll have the POLLHUP and POLLERR
events enabled even when registered with an event set of 0. To ensure
that epoll_wait doesn't poll an idle file descriptor when the underlying
connection is closed or reset then its registration is deleted from
epoll (it will be re-added again if the event set is changed)
