mp1 = 0L;    /* not used, must be zero */
mp2 = 0L;    /* not used, must be zero */
 
An application sends an MLM_QUERYCHANGED message to determine if the text in
a multiple-line entry field (MLE) has changed since the last time the
changed flag was cleared.
 
This message does not use any parameters.
 
Return Value
 
The return value is TRUE if the text has changed since the last time the
changed flag was cleared. It is FALSE if the text is unchanged or if an
error occurs.
 
Comments
 
The changed flag can also be set or cleared by using an MLM_SETCHANGED
message.
