Field        Description
────────────────────────────────────────────────────────────────────────────
 
ircStart     Specifies the rectangle from which to start enumeration, in the
             range 0 through 65535.
 
crc          Specifies the number of rectangles that can be returned in the
             arc parameter. This field must be at least 1.
 
crcReturned  Specifies the number of rectangles actually written into the
             arc parameter. A value below that specified by the start
             parameters indicates that there are no more rectangles to
             enumerate.
 
usDirection  Specifies the direction in which the (leading edge of the)
             rectangles are to be returned. This field can be one of the
             following values:
