int sds_vports (struct sds_resbuf **vlist);
Get information about this viewport.
This function returns a description of all current viewports. The description returned by the sds_vports function is a list that includes the viewport identification number, followed by viewport coordinates. These coordinates vary, depending on the setting of Tilemode:
- When TileMode = 1, the list consists of the viewports created by the VPorts command. Coordinates of the viewport's corners, ranging from (0.0, 0.0) for the lower-left corner, to (1.0, 1.0) for the upper-right corner.
- When TileMode = 0, the list consists of the viewports created with the MView command. The corners are described by paper space coordinates.
NOTE In model space, the first viewport number is #2; viewport #1 is paper space when Tilemode = 0. The current viewport is listed first.
