IStream.UnlockRegion Method

This API supports the SQL Server 2012 infrastructure and is not intended to be used directly from your code.

Removes the access restriction on a range of bytes previously restricted with the LockRegion(_ULARGE_INTEGER, _ULARGE_INTEGER, UInt32) method.

Namespace:  Microsoft.SqlServer.Dts.Runtime.Wrapper
Assembly:  Microsoft.SqlServer.DTSRuntimeWrap (in Microsoft.SqlServer.DTSRuntimeWrap.dll)

Syntax

'Declaration
Sub UnlockRegion ( _
    libOffset As _ULARGE_INTEGER, _
    cb As _ULARGE_INTEGER, _

)
'Usage
Dim instance As IStream 
Dim libOffset As _ULARGE_INTEGER 
Dim cb As _ULARGE_INTEGER 
Dim dwLockType As UInteger

instance.UnlockRegion(libOffset, cb, dwLockType)

void UnlockRegion(
    _ULARGE_INTEGER libOffset,

    uint dwLockType
)

void UnlockRegion(
    [InAttribute] _ULARGE_INTEGER libOffset, 
    [InAttribute] _ULARGE_INTEGER cb, 
    [InAttribute] unsigned int dwLockType
)

abstract UnlockRegion : 
        libOffset:_ULARGE_INTEGER * 
        cb:_ULARGE_INTEGER * 
        dwLockType:uint32 -> unit

function UnlockRegion(
    libOffset : _ULARGE_INTEGER, 
    cb : _ULARGE_INTEGER, 
    dwLockType : uint
)

Parameters

• libOffset
  Type: Microsoft.SqlServer.Dts.Runtime.Wrapper._ULARGE_INTEGER
  The byte offset for the beginning of the range.

• cb
  Type: Microsoft.SqlServer.Dts.Runtime.Wrapper._ULARGE_INTEGER
  The length, in bytes, of the range to restrict.

• dwLockType
  Type: System.UInt32
  The access restrictions previously placed on the range.
