帮帮我吧！调用VirtualFree(m_VirtualMem, 0, MEM_RELEASE)出错！
//创建内存：成功
m_VirtualMem = VirtualAlloc(0, m_lLength, MEM_RESERVE | MEM_COMMIT, PAGE_READWRITE)
//读写内存：成功
RtlMoveMemory ......
//撤除提交：成功
VirtualFree(m_VirtualMem, m_lLength, MEM_DECOMMIT)
//撤除保留：这一句老是不成功
VirtualFree(m_VirtualMem, 0, MEM_RELEASE)
LastError =87 显示为 “参数不正确！”
本人用的是 WinXP
