1. file an enhancement ticket ( for milestone 3.4.0 )
2. write the function signature in capi/geos_c.h
3. prepare a testcase
4. write the code in capi/geos_ts_c.cpp
5. write a wrapper in capi/geos_c.cpp
6. refine the testcase :)
7. attach a patch to the ticket.

Anything in capi/geos_ts_c.cpp

I guess you'd also need a function to compute locations ?
