Shared string between threadings

How do I share string between threads?

Thread nr.1 is GPS data.
Thread nr.2 is IoT communication.

I want to save the location data from thread nr.1 to shared string
On thread nr.2 the shared string is sendt to the nett.

Hi,
When you start your thread you have to provide us a tupple of arg containing a reference to your hared string and a thread.lock object to synchronise your thread.
Producer get lock, write gps data, release lock, wait new GPS data
Customer get lock, read gps data , release lock, send to network, wait new data.
Lock ensure your customer thread to not read when producer is currently writing the string.
