DrawArc
Draws an arc of circle
int DrawArc(
int xCenter,
int yCenter,
int Radius,
float StartAngle,
float ArcAngle
// X coordinate of the center point
// Y coordinate of the center point
// Radius
// Start angle of the arc
// Arc angle
);
Parameters:
xCenter
[in] X coordinate of the center point
yCenter
[in] Y coordinate of the center point
Radius
[in] Radius of the arc
StartAngle
[in] Start angle of the arc in radians
ArcAngle
[in] Arc angle in radians
Return values:
GL_OK on success.
GL_ERROR on error.
Note:
Arc is always drawn in counterclockwise direction
