IStream.UnlockRegion 方法
此 API 支持 SQL Server 2012 基础结构,但不能通过代码直接使用。
Removes the access restriction on a range of bytes previously restricted with the LockRegion(_ULARGE_INTEGER, _ULARGE_INTEGER, UInt32) method.
命名空间: Microsoft.SqlServer.Dts.Runtime.Wrapper
程序集: Microsoft.SqlServer.DTSRuntimeWrap(在 Microsoft.SqlServer.DTSRuntimeWrap.dll 中)
语法
声明
Sub UnlockRegion ( _
libOffset As _ULARGE_INTEGER, _
cb As _ULARGE_INTEGER, _
dwLockType As UInteger _
)
用法
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,
_ULARGE_INTEGER cb,
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
)
参数
- libOffset
类型:Microsoft.SqlServer.Dts.Runtime.Wrapper._ULARGE_INTEGER
The byte offset for the beginning of the range.
- cb
类型:Microsoft.SqlServer.Dts.Runtime.Wrapper._ULARGE_INTEGER
The length, in bytes, of the range to restrict.
- dwLockType
类型:System.UInt32
The access restrictions previously placed on the range.
