Function pamoja_two_link_arm_joints_for 

#[unsafe(no_mangle)]
pub unsafe extern "C" fn pamoja_two_link_arm_joints_for(
    arm: PamojaTwoLinkArm,
    x: f32,
    y: f32,
    elbow: PamojaElbow,
    out_joints: *mut PamojaJoints,
) -> bool

Finds the joint angles that put a two-link arm’s hand at a point.

Arguments

• arm - the arm.
• x - the target’s x coordinate.
• y - the target’s y coordinate.
• elbow - which way the elbow bends.
• out_joints - where to write the angles.

Returns

true with the angles written to out_joints, or false for a target out of reach, an arm with a link of no length, or a coordinate that is not a finite number.

Safety

out_joints must point to a writable PamojaJoints, or be null.
