EDITSTREAM structure (richedit.h)
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
dwCookie
Type: DWORD_PTR
Specifies an application-defined value that the rich edit control passes to the EditStreamCallback callback function specified by the pfnCallback member.
dwError
Type: DWORD
Indicates 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 the EditStreamCallback function or a code indicating that the control encountered an error.
pfnCallback
Type: EDITSTREAMCALLBACK
Pointer to an EditStreamCallback function, 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.
