GI.Gio.Interfaces.FileDescriptorBased
Description
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.
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
Exported types
newtype FileDescriptorBased Source #
Memory-managed wrapper type.
Constructors
| FileDescriptorBased (ManagedPtr FileDescriptorBased) |
Instances
class (GObject o, IsDescendantOf FileDescriptorBased o) => IsFileDescriptorBased o Source #
Type class for types which can be safely cast to FileDescriptorBased, for instance with toFileDescriptorBased.
Instances
| (GObject o, IsDescendantOf FileDescriptorBased o) => IsFileDescriptorBased o Source # | |
Defined in GI.Gio.Interfaces.FileDescriptorBased | |
toFileDescriptorBased :: (MonadIO m, IsFileDescriptorBased o) => o -> m FileDescriptorBased Source #
Cast to FileDescriptorBased, for types for which this is known to be safe. For general casts, use castTo.
