FpPoll function
Poll a file descriptor for events.
Declaration
function FpPoll(fds: ppollfd; nfds: cuint; timeout: clong): cintDescription
fpPoll waits for events on file descriptors.
fds
points to an array of
tpollfd records, each of these records
describes a file descriptor on which to wait for events. The number of
file descriptors is given by
nfds.
>timeout specifies
the maximum time (in milliseconds) to wait for events.
On timeout, the result value is 0. If an event occurred on some descriptors,
then the return value is the number of descriptors on which an event (or
error) occurred. The revents field of the tpollfd
records will contain the events for the file descriptor it described.
