PatchMesh.LockIndexBuffer Method

Language:

Locks the index buffer.

Definition

Visual Basic Public Function LockIndexBuffer( _
    ByVal typeIndex As Type, _
    ByVal flags As LockFlags, _
    ByVal ranks() As Integer _
) As Array

C# public Array LockIndexBuffer(
    Type typeIndex,
    LockFlags flags,
    int[] ranks
);

C++ public:
Array^ LockIndexBuffer(
    Type^ typeIndex,
    LockFlags flags,
    array<int>^ ranks
);

JScript public function LockIndexBuffer(
    typeIndex : Type,
    flags : LockFlags,
    ranks : int[]
) : Array;

Visual Basic	Public Function LockIndexBuffer( _ ByVal typeIndex As Type, _ ByVal flags As LockFlags, _ ByVal ranks() As Integer _ ) As Array
C#	public Array LockIndexBuffer( Type typeIndex, LockFlags flags, int[] ranks );
C++	public: Array^ LockIndexBuffer( Type^ typeIndex, LockFlags flags, array<int>^ ranks );
JScript	public function LockIndexBuffer( typeIndex : Type, flags : LockFlags, ranks : int[] ) : Array;

Parameters

typeIndex System.Type
A Type object that indicates the type of array data to return. This can be a value type or any type that contains only value types.

flags Microsoft.DirectX.Direct3D.LockFlags
Zero or more LockFlags that describe the type of lock to perform. For this method, the valid flags are Discard, NoDirtyUpdate, NoSysLock, and ReadOnly. For a description of the flags, see LockFlags.

ranks System.Int32[]
Array of one to three Int32 values that indicate the dimensions of the returning Array .

Return Value

System.Array
An Array that represents the locked index buffer.

Remarks

The index buffer is usually locked, written to, and then unlocked for reading. Patch mesh index buffers are 16-bit buffers.
