Definition

Namespace:

System.IO

Assembly:

System.Runtime.InteropServices.dll

Source:

UnmanagedMemoryAccessor.cs

Sets the initial values for the accessor.

protected:
 void Initialize(System::Runtime::InteropServices::SafeBuffer ^ buffer, long offset, long capacity, System::IO::FileAccess access);

protected void Initialize (System.Runtime.InteropServices.SafeBuffer buffer, long offset, long capacity, System.IO.FileAccess access);

member this.Initialize : System.Runtime.InteropServices.SafeBuffer * int64 * int64 * System.IO.FileAccess -> unit

Protected Sub Initialize (buffer As SafeBuffer, offset As Long, capacity As Long, access As FileAccess)

Parameters

buffer

SafeBuffer

The buffer to contain the accessor.

offset

Int64

The byte at which to start the accessor.

capacity

Int64

The size, in bytes, of memory to allocate.

access

FileAccess

The type of access allowed to the memory. The default is ReadWrite.

ArgumentNullException

buffer is null.

ArgumentOutOfRangeException

offset or capacity is less than zero.
