Important Notice
The pages on this site contain documentation for very old MS-DOS software,

you should not rely on the information found here, as it will be woefully
out of date.
getarcinfo
◄Summary► ◄Example► ◄Up► ◄Contents► ◄Index► ◄Back►
────────────────────────────────────────────────────────────────────────────
The getarcinfo function determines the endpoints in viewport
coordinates of the most recently drawn arc or pie.
If successful, the getarcinfo function updates the <start> and
<end> xycoord structures to contain the endpoints (in viewport
coordinates) of the arc drawn by the most recent call to one of the
arc or pie functions.
In addition, <fillpoint> specifies a point from which a pie can
be filled. This is useful for filling a pie in a color different
from the border color. To change colors, use the setcolor
function after calling getarcinfo. Use the coordinates in
<fillpoint>, along with the color, as arguments for the floodfill
procedure.
Return Value
The getarcinfo function returns a nonzero value if successful. If
neither the arc nor the pie function has been successfully called
since the last time the screen was cleared or a new graphics mode
or viewport was selected, the getarcinfo function returns 0.
