我想在现金操作期间配置特定的票据类型

输入参数应采用以下格式：LPUSHORT lpusNoteIDs;

当我执行以下命令时，我收到无效数据错误（-52）

LPUSHORT* lpusNoteIDs;  
lpusNoteIDs = (LPUSHORT*)malloc(7*sizeof(LPUSHORT));
for(int i =0;i<7;i++)
{
    lpusNoteIDs[i]=(LPUSHORT)malloc(sizeof(USHORT));
}

lpusNoteIDs[0] = (LPUSHORT)0x2700;
lpusNoteIDs[1] = (LPUSHORT)0x2710;
lpusNoteIDs[2] = (LPUSHORT)0x2701;
lpusNoteIDs[3] = (LPUSHORT)0x2711;
lpusNoteIDs[4] = (LPUSHORT)0x2721;
lpusNoteIDs[5] = (LPUSHORT)0x2732;
lpusNoteIDs[6] = (LPUSHORT)0x2704;
hResult = WFSExecute(hService, WFS_CMD_CIM_CONFIGURE_NOTETYPES, (LPVOID)lpusNoteIDs, 400000, &res);
return (int)hResult;

我什至尝试过下面的代码，但它给了我同样的错误

LPUSHORT* lpusNoteIDs;
USHORT abc[]={1000,9985,10001,10017,10034,9988};
lpusNoteIDs=(LPUSHORT*)abc;
hResult = WFSExecute(hService, WFS_CMD_CIM_CONFIGURE_NOTETYPES,(LPVOID)lpusNoteIDs, 600000, &res);
return (int)hResult;

在 CIM 服务提供商实施规范文档中它说：

lpusNoteIDs :-指向以 NULL 结尾的无符号短裤列表，其中包含钞票的票据 ID

关于必须如何传递值的任何帮助都将非常有用。在此先感谢。

您必须使用 WFMAllocate 和 WFMAllocateMore 函数为 XFS 结构分配内存，以便在应用程序和服务提供者之间传输它。您的示例如下：

LPUSHORT lpusNoteIDs = NULL;
const int countNotes = 7;
// Always use WFMAllocate* functions for XFS memory allocation
WFSRESULT hr = WFMAllocateBuffer(sizeof(USHORT)*(countNotes+1), WFS_MEM_ZEROINIT|WFS_MEM_SHARE, (void**)&lpusNoteIDs);

// Fill note ID's
lpusNoteIDs[0] = (USHORT)0x2700;
lpusNoteIDs[1] = (USHORT)0x2710;
lpusNoteIDs[2] = (USHORT)0x2701;
lpusNoteIDs[3] = (USHORT)0x2711;
lpusNoteIDs[4] = (USHORT)0x2721;
lpusNoteIDs[5] = (USHORT)0x2732;
lpusNoteIDs[6] = (USHORT)0x2704;

hr = WFSExecute(hService, WFS_CMD_CIM_CONFIGURE_NOTETYPES, (LPVOID)&lpusNoteIDs, 400000, &res);
