Remarks

COM Signature

From textmgr.idl:

HRESULT IVsFullTextScanner::FullTextRead(
   [out] WCHAR **ppszText,
   [out] long *piLength
);

A pointer to a text buffer is returned in ppszText parameter. The piLength parameter is then filled with the length of the buffer pointed to by *ppsztext.

Note

The text buffer is created by the IVsFullTextScanner object and the buffer must persist for the life of the IVsFullTextScanner object or until the CloseFullTextScan method is called. If you are implementing this interface in managed code and you need the caller to dispose of the string, implement the IVsCoTaskMemFreeMyStrings interface on the IVsFullTextScanner 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.
