CreateEditableStream
The CreateEditableStream
function creates an editable stream. Use this function before using other
stream editing functions.
STDAPI CreateEditableStream(

PAVISTREAM
* ppsEditable, |

PAVISTREAM
psSource |
|

); |

Parameters
ppsEditable
Address to
contain the new stream handle.
psSource
Handle of the
stream supplying data for the new stream. Specify NULL to create an empty
editable string that you can copy and paste data into.
Return Values
Returns zero
if successful or an error otherwise.
Remarks
The stream
pointer returned in ppsEditable must be used as the source stream in the
other stream editing functions.
Internally,
this function creates tables to keep track of changes to a stream. The original
stream is never changed by the stream editing functions. The stream pointer
created by this function can be used in any AVIFile function that accepts
stream pointers. You can use this function on the same stream multiple times. A
copy of a stream is not affected by changes in another copy.
