Remarks

COM Signature

From textmgr.idl:

HRESULT IVsPersistentTextImage::Image_FullTextRead(
   [out] const WCHAR **ppszText,
   [out] long *piLength
);

Note

The text buffer is created by the IVsPersistentTextImage object and the buffer must persist for the life of the IVsPersistentTextImage object or until the Image_CloseFullTextScan method is called.

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 IVsPersistentTextImage 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.
