I think that should be possible to use the geometry feature of the
vector api of pygrass,

>>> from grass import pygrass
>>> from pygrass.vector.geometry import Point, Line
>>> pnt = Point(10, 100)
>>> line = Line([(0, 0), (1, 1), (2, 0), (1, -1)])
>>> line.c_points  # return the ctypes pointer to the line_points struct
<grass.lib.ctypes_preamble.LP_struct_line_pnts object at 0x2aa1440>

even if is not deeply tested...

get more example from here:
