Structure used for scatter/gather data output.
You generally pass in an array of GOutputVectors
and the operation will use all the buffers as if they were
one buffer.
Since: 2.22

Methods
Properties
buffer
Pointer to a buffer of data to read.
clearOutputVectorBuffer :: MonadIO m => OutputVector -> m () Source #
Set the value of the “buffer
” field to Nothing
.
When overloading is enabled, this is equivalent to
clear
#buffer
getOutputVectorBuffer :: MonadIO m => OutputVector -> m (Ptr ()) Source #
Get the value of the “buffer
” field.
When overloading is enabled, this is equivalent to
get
outputVector #buffer
setOutputVectorBuffer :: MonadIO m => OutputVector -> Ptr () -> m () Source #
Set the value of the “buffer
” field.
When overloading is enabled, this is equivalent to
set
outputVector [ #buffer:=
value ]
size
the size of buffer
.
getOutputVectorSize :: MonadIO m => OutputVector -> m Word64 Source #
Get the value of the “size
” field.
When overloading is enabled, this is equivalent to
get
outputVector #size
setOutputVectorSize :: MonadIO m => OutputVector -> Word64 -> m () Source #
Set the value of the “size
” field.
When overloading is enabled, this is equivalent to
set
outputVector [ #size:=
value ]
