GI.Gio.Structs.InputVector

Structure used for scatter/gather data input. You generally pass in an array of GInputVectors and the operation will store the read data starting in the first buffer, switching to the next as needed.

Since: 2.22

Exported types

newtype InputVector

Memory-managed wrapper type.

Constructors

InputVector (ManagedPtr InputVector)

Instances

WrappedPtr InputVector

Defined in GI.Gio.Structs.InputVector

Methods

wrappedPtrCalloc :: IO (Ptr InputVector)

wrappedPtrCopy :: InputVector -> IO InputVector

wrappedPtrFree :: Maybe (GDestroyNotify InputVector)

tag ~ AttrSet => Constructible InputVector tag

Defined in GI.Gio.Structs.InputVector

Methods

new :: MonadIO m => (ManagedPtr InputVector -> InputVector) -> [AttrOp InputVector tag] -> m InputVector

newZeroInputVector :: MonadIO m => m InputVector

Construct a InputVector struct initialized to zero.

noInputVector :: Maybe InputVector

A convenience alias for Nothing :: Maybe InputVector.

Properties

buffer

Pointer to a buffer where data will be written.

clearInputVectorBuffer :: MonadIO m => InputVector -> m ()

Set the value of the “buffer” field to Nothing. When overloading is enabled, this is equivalent to

clear #buffer

getInputVectorBuffer :: MonadIO m => InputVector -> m (Ptr ())

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

get inputVector #buffer

setInputVectorBuffer :: MonadIO m => InputVector -> Ptr () -> m ()

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

set inputVector [ #buffer := value ]

size

the available size in buffer.

getInputVectorSize :: MonadIO m => InputVector -> m Word64

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

get inputVector #size

setInputVectorSize :: MonadIO m => InputVector -> Word64 -> m ()

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

set inputVector [ #size := value ]
