PipeWriter.GetMemory(Int32) Method

Definition

Namespace:

System.IO.Pipelines

Assembly:

Package:

System.IO.Pipelines v9.0.0-rc.2.24473.5

Source:

PipeWriter.cs

Returns a Memory<T> to write to that is at least the requested size, as specified by the sizeHint parameter.

public abstract Memory<byte> GetMemory (int sizeHint = 0);

abstract member GetMemory : int -> Memory<byte>

Public MustOverride Function GetMemory (Optional sizeHint As Integer = 0) As Memory(Of Byte)

Parameters

sizeHint

Int32

The minimum length of the returned Memory<T>. If 0, a non-empty memory buffer of arbitrary size is returned.

Returns

Memory<Byte>

A memory buffer of at least sizeHint bytes. If sizeHint is 0, returns a non-empty buffer of arbitrary size.

Implements

GetMemory(Int32)

Exceptions

OutOfMemoryException

The requested buffer size is not available.

Remarks

There is no guarantee that successive calls will return the same buffer or the same-sized buffer.

This method never returns Memory<T>.Empty, but it throws an OutOfMemoryException if the requested buffer size is not available.

You must request a new buffer after calling Advance to continue writing more data; you cannot write to a previously acquired buffer.
