CX_MetadataItem struct

Structure that contains the metadata item parameters, used by the CX_GetMetadataItem callback.

Syntax


struct CX_MetadataItem
{
   CX_MetadataItem() { ZeroMemory(this, sizeof(*this)); };

   DWORD dwFlags; 
   char* pszID; 
   void* pData; 
   UINT  cbData;
   UINT  uDataType; 
};

Members

dwFlags

Type: DWORD

Flags (set to 0)

pszID

Type: char*

Item identifier (CX_MDI)

pData

Type: void*

Pointer to item value data

cbData

Type: UINT

Length of item value data

uDataType

Type: UINT

Type of item value data (CX_MDT). This affects what kind of data is pointed at by pData.

Remarks

pszID is set to a Metadata item identifier (CX_MDI) by the plug-in. pData is allocated by the host application using HeapAlloc() on the process heap. The plug-in is responsible for freeing pData using HeapFree(GetProcessHeap(), 0, pData) (used in the CX_GetMetadataItem and CX_GetFileMetadataItem callback functions).
