The GetPolyFillMode function retrieves the current polygon fill mode.
int GetPolyFillMode(
HDC hdc // handle to device context
);
If the function succeeds, the return value specifies the polygon fill mode, which can be either of the following values:
| Value | Meaning |
|---|---|
| ALTERNATE | Selects alternate mode (fills area between odd-numbered and even-numbered polygon sides on each scan line). |
| WINDING | Selects winding mode (fills any region with a nonzero winding value). |
If an error occurs, the return value is zero.
