Description

GFileDescriptorBased is an interface for file descriptor based IO.

It 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 or the GioUnix-2.0 GIR namespace when using it.

Since: 2.24

Synopsis

newtype FileDescriptorBased = FileDescriptorBased (ManagedPtr FileDescriptorBased)
class (GObject o, IsDescendantOf FileDescriptorBased o) => IsFileDescriptorBased o
toFileDescriptorBased :: (MonadIO m, IsFileDescriptorBased o) => o -> m FileDescriptorBased
fileDescriptorBasedGetFd :: (HasCallStack, MonadIO m, IsFileDescriptorBased a) => a -> m Int32
