| -> m () |
Initializes fd. Alternatively you can initialize it with
GST_POLL_FD_INIT.
Properties
fd
a file descriptor
getPollFDFd :: MonadIO m => PollFD -> m Int32 Source #
Get the value of the “fd” field.
When overloading is enabled, this is equivalent to
get pollFD #fd
setPollFDFd :: MonadIO m => PollFD -> Int32 -> m () Source #
Set the value of the “fd” field.
When overloading is enabled, this is equivalent to
setpollFD [ #fd:=value ]
