Syntax

'Declaration
Function GetSourceContext ( _
    index As UInteger, _
    pszFilename As IntPtr, _
    <OutAttribute> ByRef pulLineNum As UInteger _
) As Integer

int GetSourceContext(
    uint index,
    IntPtr pszFilename,
    out uint pulLineNum
)

int GetSourceContext(
    [InAttribute] unsigned int index, 
    [InAttribute] IntPtr pszFilename, 
    [OutAttribute] unsigned int% pulLineNum
)

abstract GetSourceContext : 
        index:uint32 * 
        pszFilename:IntPtr * 
        pulLineNum:uint32 byref -> int

function GetSourceContext(
    index : uint, 
    pszFilename : IntPtr, 
    pulLineNum : uint
) : int

Parameters

index
Type: System.UInt32
[in] Specifies the index of the list item of interest.

pszFilename
Type: System.IntPtr
[out] Pointer to a null terminated string containing the file name. You must allocate this buffer and free it on the list's final Release, but you can reuse this buffer for multiple calls to this method.

pulLineNum
Type: System.UInt32%
[out] Specifies a line number.

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 vsshell.idl:

HRESULT IVsObjectList::GetSourceContext(
   [in] ULONG Index,
   [out] const WCHAR **pszFileName,
   [out] ULONG *pulLineNum
);

This method is used to display the source file and line number in the find symbol results window. You can return E_NOTIMPL if you don't want to display this information.

Note

The text buffer is created by the IVsObjectList object and the buffer must persist for the life of the IVsObjectList object.

If you are implementing this interface in managed code and you need to have the string disposed of by the caller, implement the IVsCoTaskMemFreeMyStrings interface on the IVsObjectList interface.

.NET Framework Security

Full trust for the immediate caller. This member cannot be used by partially trusted code. For more information, see Using Libraries from Partially Trusted Code.
