Type: System.Threading.NativeOverlapped

System.Threading.NativeOverlapped Structure

Assembly: Mscorlib.dll
Namespace: System.Threading

Summary: Provides an explicit layout that is visible from unmanaged code and that will have the same layout as the Win32 OVERLAPPED structure with additional reserved fields at the end.

C# Syntax:


        public struct NativeOverlapped

Remarks

The NativeOverlapped.NET Framework value type represents an unmanaged version of the Win32 OVERLAPPED structure. The layout of this structure must be identical to OVERLAPPED. Four additional DWORDs are reserved at the end.

System.Threading.NativeOverlapped Member List:

Public Fields

EventHandle	Specifies the handle to an event set to the signaled state when the operation is complete. The calling process must set this member either to zero or to a valid event handle before calling any overlapped functions.
InternalHigh	Specifies the length of the data transferred. Reserved for operating system use.
InternalLow	Specifies a system-dependent status. Reserved for operating system use.
OffsetHigh	Specifies the high word of the byte offset at which to start the transfer.
OffsetLow	Specifies a file position at which to start the transfer.

Public Methods

Equals (inherited from System.ValueType)	See base class member description: System.ValueType.Equals Indicates whether this instance and a specified object are equal.
GetHashCode (inherited from System.ValueType)	See base class member description: System.ValueType.GetHashCode Returns the hash code for this instance.
GetType (inherited from System.Object)	See base class member description: System.Object.GetType Derived from System.Object, the primary base class for all objects.
ToString (inherited from System.ValueType)	See base class member description: System.ValueType.ToString Returns the fully qualified type name of this instance.

Protected Methods

Finalize (inherited from System.Object)	See base class member description: System.Object.Finalize Derived from System.Object, the primary base class for all objects.
MemberwiseClone (inherited from System.Object)	See base class member description: System.Object.MemberwiseClone Derived from System.Object, the primary base class for all objects.

System.Threading.NativeOverlapped Member Details

Field: EventHandle

Summary: Specifies the handle to an event set to the signaled state when the operation is complete. The calling process must set this member either to zero or to a valid event handle before calling any overlapped functions.

C# Syntax:


            public int EventHandle;

Return to top

Field: InternalHigh

Summary: Specifies the length of the data transferred. Reserved for operating system use.

C# Syntax:


            public int InternalHigh;

Return to top

Field: InternalLow

Summary: Specifies a system-dependent status. Reserved for operating system use.

C# Syntax:


            public int InternalLow;

Return to top

Field: OffsetHigh

Summary: Specifies the high word of the byte offset at which to start the transfer.

C# Syntax:


            public int OffsetHigh;

Remarks

This member is ignored when reading from or writing to named pipes and communications devices and in those cases its value should be zero.

Return to top

Field: OffsetLow

Summary: Specifies a file position at which to start the transfer.

C# Syntax:


            public int OffsetLow;

Remarks

The file position is a byte offset from the start of the file. The calling process sets this member before calling the OR function. This member is ignored when reading from or writing to named pipes and communications devices, and in those cases its value should be zero.

Method: Equals(
object obj
)

Inherited
See base class member description: System.ValueType.Equals

Summary: Indicates whether this instance and a specified object are equal.

C# Syntax:


            public override bool Equals(
   object obj
);

Parameters:

obj

Another object to compare to.

Return Value:: true if obj and this instance are the same type and represent the same value; otherwise, false.

Return to top

Method: Finalize()

Inherited
See base class member description: System.Object.Finalize

C# Syntax:


            ~NativeOverlapped();

Method: GetHashCode()

Inherited
See base class member description: System.ValueType.GetHashCode

Summary: Returns the hash code for this instance.

C# Syntax:


            public override int GetHashCode();

Return Value:: A 32-bit signed integer that is the hash code for this instance.

Remarks

The ValueType.GetHashCode method applies to types derived from ValueType. One or more fields of the derived type is used to calculate the return value. If one or more of those fields contains a mutable value, the return value might be unpredictable, and unsuitable for use as a key in a hash table.

For more information, see Object.GetHashCode, and Hashtable.

Method: MemberwiseClone()

Inherited

Method: ToString()

Inherited
See base class member description: System.ValueType.ToString

Summary: Returns the fully qualified type name of this instance.

C# Syntax:


            public override string ToString();

Return Value:: A String containing a fully qualified type name.
