PipeWriter.GetSpan(Int32) Method

Definition

Namespace:

System.IO.Pipelines

Assembly:

Package:

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

Source:

PipeWriter.cs

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

public abstract Span<byte> GetSpan (int sizeHint = 0);

abstract member GetSpan : int -> Span<byte>

Public MustOverride Function GetSpan (Optional sizeHint As Integer = 0) As Span(Of Byte)

Parameters

sizeHint

Int32

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

Returns

Span<Byte>

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

Implements

GetSpan(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 Span<T>.Empty, but it throws an OutOfMemoryException if the requested buffer size is not available.

You must request a new buffer after calling Advance(Int32) to continue writing more data; you cannot write to a previously acquired buffer.
