EDITSTREAM StructureTheEDITSTREAMstructure contains information that an application passes to a rich edit control in a EM_STREAMIN or EM_STREAMOUT message. The rich edit control uses the information to transfer a stream of data into or out of the control.
Syntax
typedef struct _editstream { DWORD_PTR dwCookie; DWORD dwError; EDITSTREAMCALLBACK pfnCallback;} EDITSTREAM;Members
dwCookieSpecifies an application-defined value that the rich edit control passes to the EditStreamCallback callback function specified by thepfnCallbackmember.dwErrorIndicates the results of the stream-in (read) or stream-out (write) operation. A value of zero indicates no error. A nonzero value can be the return value of theEditStreamCallbackfunction or a code indicating that the control encountered an error.pfnCallbackPointer to anEditStreamCallbackfunction, which is an application-defined function that the control calls to transfer data. The control calls the callback function repeatedly, transferring a portion of the data with each call. Structure Information
