Routine Description:
|
|
|
|
Call out to a SP_FILE_CALLBACK routine, translating arguments from
|
|
Unicode to ANSI as necessary, and marshalling data back into Unicode
|
|
as necessary.
|
|
|
|
Conversions and marshalling occur only for messages we recognize
|
|
(ie, that are in the MsgThunkData array). Unrecognized messages
|
|
are assumed to be private and are passed through unchanged.
|
|
|
|
If a Unicode->ANSI conversion fails due to an out of memory condition,
|
|
this routine sets last error to ERROR_NOT_ENOUGH_MEMORY and returns
|
|
the value specified in the relevent MsgThunkData structure.
|
|
|
|
Arguments:
|
|
|
|
LogContext - context for logging errors
|
|
|
|
MsgHandler - supplies pointer to callback routine. Can be either
|
|
a routine expecting ANSI args or Unicode args, as specified
|
|
by MsgHandlerIsNativeCharWidth.
|
|
|
|
MsgHandlerIsNativeCharWidth - supplies flag indicating whether callback
|
|
functionexpects Unicode (TRUE) or ANSI (FALSE) arguments.
|
|
|
|
Context - supplies context data meaningful to the callback
|
|
routine. Not interpreted by this routine, merely passed on.
|
|
|
|
Notification - supplies notification code to be passed to the callback.
|
|
|
|
Param1 - supplies first notification-specific parameter to be passed
|
|
to the callback.
|
|
|
|
Param2 - supplies second notification-specific parameter to be passed
|
|
to the callback.
|
|

Return Value:
|
|

|
Return code specific to the notification.

Unicode or Unicode to ANSI as necessary. Allocates all required memory
|
|
and performs conversions.
|
|
|
|
Arguments:
|
|
|
|
StructType - supplies type of data represented by Param.
|
|
|
|
Param - supplies parameter to be converted.
|
|
|
|
NewParam - receives new parameter. Caller should free via
|
|
pUnthunkSetupMsgParam when done.
|
|
|
|
ToAnsi - if FALSE, Param is to be converted from ANSI to Unicode.
|
|
If TRUE, Param is to be converted from Unicode to ANSI.
|
|
|
|
Return Value:
|
|
|
|
Boolean value indicating whether conversion occured successfully.
|
|
If FALSE, the caller can assume out of memory.

Routine Description:
|
|
|
|
Marshal data output by a callback function back into the original
|
|
Unicode or ANSI structure. Also, free the temporary structure and all
|
|
its resources.
|
|
|
|
Arguments:
|
|
|
|
StructType - supplies type of data being operated on.
|
|
|
|
OriginalParam - supplies original parameter. DWORD fields and
|
|
in-place strings in this structure will be updated by this routine.
|
|
|
|
ThunkedParam - supplies temporary ANSI or Unicode parameter.
|
|
|
|
FreeOnly - if TRUE, no marshalling occurs but ThunkedParam will be freed.
|
|
|
|
Return Value:
|

None.
