Python struct_setfield_float Examples

Example #1

     POINT = lltype.Struct('POINT', ('x', rffi.DOUBLE), ('y', rffi.DOUBLE))
     y_ofs = 8
     p = lltype.malloc(POINT, flavor='raw')
     p.x = 123.4
     p.y = 567.8
     addr = rffi.cast(rffi.VOIDP, p)
     assert struct_getfield_float(types.double, addr, 0) == 123.4
     assert struct_getfield_float(types.double, addr, y_ofs) == 567.8
     #
     struct_setfield_float(types.double, addr, 0, 321.0)
     struct_setfield_float(types.double, addr, y_ofs, 876.5)
     assert p.x == 321.0
     assert p.y == 876.5
     #
     lltype.free(p, flavor='raw')
