Namespace:

System.IO

Assembly:

System.Runtime.InteropServices.dll

Initializes a new instance of the UnmanagedMemoryAccessor class.

Overloads

UnmanagedMemoryAccessor()	Initializes a new instance of the UnmanagedMemoryAccessor class.
UnmanagedMemoryAccessor(SafeBuffer, Int64, Int64)	Initializes a new instance of the UnmanagedMemoryAccessor class with a specified buffer, offset, and capacity.
UnmanagedMemoryAccessor(SafeBuffer, Int64, Int64, FileAccess)	Initializes a new instance of the UnmanagedMemoryAccessor class with a specified buffer, offset, capacity, and access right.

UnmanagedMemoryAccessor()

Source:

UnmanagedMemoryAccessor.cs

Initializes a new instance of the UnmanagedMemoryAccessor class.

protected:
 UnmanagedMemoryAccessor();

protected UnmanagedMemoryAccessor ();

Protected Sub New ()

UnmanagedMemoryAccessor(SafeBuffer, Int64, Int64)

Source:

UnmanagedMemoryAccessor.cs

Initializes a new instance of the UnmanagedMemoryAccessor class with a specified buffer, offset, and capacity.

public:
 UnmanagedMemoryAccessor(System::Runtime::InteropServices::SafeBuffer ^ buffer, long offset, long capacity);

public UnmanagedMemoryAccessor (System.Runtime.InteropServices.SafeBuffer buffer, long offset, long capacity);

new System.IO.UnmanagedMemoryAccessor : System.Runtime.InteropServices.SafeBuffer * int64 * int64 -> System.IO.UnmanagedMemoryAccessor

Public Sub New (buffer As SafeBuffer, offset As Long, capacity As Long)

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.

Exceptions

ArgumentException

offset plus capacity is greater than buffer.

ArgumentNullException

buffer is null.

ArgumentOutOfRangeException

offset or capacity is less than zero.

InvalidOperationException

offset plus capacity would wrap around the high end of the address space.

UnmanagedMemoryAccessor(SafeBuffer, Int64, Int64, FileAccess)

Source:

UnmanagedMemoryAccessor.cs

Initializes a new instance of the UnmanagedMemoryAccessor class with a specified buffer, offset, capacity, and access right.

public:
 UnmanagedMemoryAccessor(System::Runtime::InteropServices::SafeBuffer ^ buffer, long offset, long capacity, System::IO::FileAccess access);

public UnmanagedMemoryAccessor (System.Runtime.InteropServices.SafeBuffer buffer, long offset, long capacity, System.IO.FileAccess access);

new System.IO.UnmanagedMemoryAccessor : System.Runtime.InteropServices.SafeBuffer * int64 * int64 * System.IO.FileAccess -> System.IO.UnmanagedMemoryAccessor

Public Sub New (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.

Exceptions

ArgumentException

offset plus capacity is greater than buffer.

ArgumentNullException

buffer is null.

ArgumentOutOfRangeException

offset or capacity is less than zero.

-or-

access is not a valid MemoryMappedFileAccess enumeration value.

InvalidOperationException

offset plus capacity would wrap around the high end of the address space.
