GI.Gio.Interfaces.FileDescriptorBased

FileDescriptorBased is implemented by streams (implementations of InputStream or OutputStream) that are based on file descriptors.

Note that <gio/gfiledescriptorbased.h> belongs to the UNIX-specific GIO interfaces, thus you have to use the gio-unix-2.0.pc pkg-config file when using it.

Exported types

newtype FileDescriptorBased

Memory-managed wrapper type.

Constructors

FileDescriptorBased (ManagedPtr FileDescriptorBased)

Instances

GObject FileDescriptorBased

Methods

gobjectType :: FileDescriptorBased -> IO GType

IsObject FileDescriptorBased

noFileDescriptorBased :: Maybe FileDescriptorBased

A convenience alias for Nothing :: Maybe FileDescriptorBased.

class GObject o => IsFileDescriptorBased o

Type class for types which can be safely cast to FileDescriptorBased, for instance with toFileDescriptorBased.

toFileDescriptorBased :: (MonadIO m, IsFileDescriptorBased o) => o -> m FileDescriptorBased

Cast to FileDescriptorBased, for types for which this is known to be safe. For general casts, use castTo.

Methods

getFd

fileDescriptorBasedGetFd

Arguments

:: (HasCallStack, MonadIO m, IsFileDescriptorBased a)

=> a

fdBased: a FileDescriptorBased.

-> m Int32

Returns: The file descriptor

Gets the underlying file descriptor.
