    uint celt,
    VSSAVETREEITEM[] rgSaveTreeItems,
    out uint pcActual
)

int GetRelatedSaveTreeItems(

Parameters

• saveItem
  Type: Microsoft.VisualStudio.Shell.Interop.VSSAVETREEITEM

  [in] Pointer to a VSSAVETREEITEM structure containing information about the item to check for related items.

• celt
  Type: System.UInt32

  [in] Zero or the number of items in rgSaveTreeItems. See Remarks.

• rgSaveTreeItems
  Type: []

  [in, out] Pointer to an array of VSSAVETREEITEM structures containing information about related items to save.

• pcActual
  Type: System.UInt32%

  [out] Pointer to an integer that is the number of related items to save or the number of elements in rgSaveTreeItems.

Return Value

Type: System.Int32

If the method succeeds, it returns S_OK. If it fails, it returns an error code.

Remarks

COM Signature

From vsshell80.idl:

HRESULT GetRelatedSaveTreeItems(
    [in] VSSAVETREEITEM saveItem,
    [in] ULONG celt,
    [in, out, size_is(celt)] VSSAVETREEITEM rgSaveTreeItems[],
    [out] ULONG *pcActual
);

Notes for Implementers

The method can return either the number of related save items, or it can return information about the related save items. The method returns the number of VSSAVETREEITEM items in pcActual if celt is zero and pcActual is not a null reference (Nothing in Visual Basic).

This behavior yields a common pattern of finding the number of related items and then retrieving information about the items, as in the following code. The code omits error checking for readability.

hr = pIVsHasRelatedSaveItems->GetRelatedSaveTreeItems(saveItem, 
        0, NULL, &cExpected);
prgSaveTreeItems = ::CoTaskMemAlloc(
        cExpected * sizeof(VSSAVETREEITEM));
hr = pIVsHasRelatedSaveItems->GetRelatedSaveTreeItems(saveItem,
        cExpected, prgSaveTreeItems, &cActual);
