In the program ArduPilot_EasyStar_V22 there is a declaration:
char *brkb, *pEnd;
In GPS_NEMA.pde, there is a statement:
token = strtok_r(gps_buffer, search, &brkb);
where the string is parsed by looking for the data between commas.
Where is &brkb defined as the comma character. I can't find it in the program files or headers?
