Arguments

:: (HasCallStack, MonadIO m)

=> PollFD

fd: a PollFD

-> m ()

Initializes fd. Alternatively you can initialize it with GST_POLL_FD_INIT.

Properties

fd

a file descriptor

getPollFDFd :: MonadIO m => PollFD -> m Int32

Get the value of the “fd” field. When overloading is enabled, this is equivalent to

get pollFD #fd

setPollFDFd :: MonadIO m => PollFD -> Int32 -> m ()

Set the value of the “fd” field. When overloading is enabled, this is equivalent to

set pollFD [ #fd := value ]
