) -> c_int
Expand description

Append a #POINTARRAY, pa2 to the end of an existing #POINTARRAY, pa1.

If gap_tolerance is >= 0 then the end point of pa1 will be checked for being within gap_tolerance 2d distance from start point of pa2 or an error will be raised and LW_FAILURE returned. A gap_tolerance < 0 disables the check.

If end point of pa1 and start point of pa2 are 2d-equal, then pa2 first point will not be appended.
