Methods

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

Properties

vDouble

the field for holding floating point values

getTypeCValueVDouble :: MonadIO m => TypeCValue -> m Double

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

get typeCValue #vDouble

setTypeCValueVDouble :: MonadIO m => TypeCValue -> Double -> m ()

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

set typeCValue [ #vDouble := value ]

vInt

the field for holding integer values

getTypeCValueVInt :: MonadIO m => TypeCValue -> m Int32

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

get typeCValue #vInt

setTypeCValueVInt :: MonadIO m => TypeCValue -> Int32 -> m ()

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

set typeCValue [ #vInt := value ]

vInt64

the field for holding 64 bit integer values

getTypeCValueVInt64 :: MonadIO m => TypeCValue -> m Int64

Get the value of the “v_int64” field. When overloading is enabled, this is equivalent to

get typeCValue #vInt64

setTypeCValueVInt64 :: MonadIO m => TypeCValue -> Int64 -> m ()

Set the value of the “v_int64” field. When overloading is enabled, this is equivalent to

set typeCValue [ #vInt64 := value ]

vLong

the field for holding long integer values

getTypeCValueVLong :: MonadIO m => TypeCValue -> m CLong

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

get typeCValue #vLong

setTypeCValueVLong :: MonadIO m => TypeCValue -> CLong -> m ()

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

set typeCValue [ #vLong := value ]

vPointer

the field for holding pointers

clearTypeCValueVPointer :: MonadIO m => TypeCValue -> m ()

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

clear #vPointer

getTypeCValueVPointer :: MonadIO m => TypeCValue -> m (Ptr ())

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

get typeCValue #vPointer

setTypeCValueVPointer :: MonadIO m => TypeCValue -> Ptr () -> m ()

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

set typeCValue [ #vPointer := value ]
