The GetBoundsRect function returns the current accumulated bounding rectangle for the specified device context.
hdc
Identifies the device context to return the bounding rectangle for.
lprcBounds
Points to a buffer that will receive the current bounding rectangle. The rectangle is returned in logical coordinates.
flags
Specifies whether the bounding rectangle is to be cleared after it is returned. This parameter can be DCB_RESET, to clear the rectangle. Otherwise, it should be zero.
The return value is DCB_SET if the bounding rectangle is not empty. Otherwise, it is DCB_RESET.
To ensure that the bounding rectangle is empty, check both the DCB_RESET bit and the DCB_ACCUMULATE bit in the return value. If DCB_RESET is set and DCB_ACCUMULATE is not, the bounding rectangle is empty.
