ppszText: String

[out] Range of the text buffer to read.

piLength: Int32

[out] Length of text to read from the buffer.

Remarks

COM Signature

From textmgr.idl:

HRESULT IVsTextScanner::Read(  
   [out] WCHAR **ppszText,  
   [out] long *piLength  
);

The parameter piLength is an integer value for the length of text pointed to by ppszText. If the value is zero, there is no more text.

Note

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