The MimeSetMessageHeaderEx function adds or updates a
header field in the specified message.
Parameters
- hMessage
- Handle to the message.
- nMessagePart
- An integer value which specifies which part of the message the
header should be set or modified in. A value of zero sets a header
value in the main message header block, while a value greater than
zero sets the header value in that specific part of a multipart
message. A value of -1 specifies that the header value should be
set in the current message part.
- lpszHeader
- Pointer to a null-terminated string which specifies the header
field that will be added or updated.
- lpszValue
- Pointer to a null-terminated string which specifies the value
for the header field. This pointer may be NULL, which causes the
header field to be removed from the message.
- dwReserved
- A reserved parameter. This value should always be zero.
Return Value
If the function succeeds, the return value is non-zero. If the
function fails, the return value is zero. To get extended error
information, call MimeGetLastError.
