I want to the velocity vector for the first node point to the wall. Can I use wallDis

I have a particle P(xp,yp,zp) somewhere in the mesh. I need the index of the nearest wall cell to my point P so I can calculate the velocity vector of the first node point to the wall. I first thought of using the library "wallDist.H". It unfortunately only returns the distance of the closest cell at the wall and not the index of this latter.
in other words:
//create field containg wall distances
volScalarField wd = wallDist(mesh)
//create field of the indexes of the closest wall cells
volField<label> = wd.labelOfTheWallCells() <- how do I get this?
Is there any such functions already implemented in OF? If not, what could I do to achieve this ?
