This function is used to get a mouse message. If mouse message queue is empty, wait until a mouse message is available for retrieval.
Returns the structure that holds the mouse message.
By default, consecutive mouse clicks are recognized as a series of click events. If you want two consecutive mouse clicks to recognize as a double-click event, specify the flag bit EW_DBLCLKS when you create the drawing window.
This function is obsolete and is declared only in graphics.h. It is recommended that use getmessage instead of the function.
