If parsing the log or calling chronyc is not acceptable, you could
implement the tracking command in your program.
The request is one 104 bytes long UDP packet sent to localhost:323.
The first 6 bytes are 0x06 0x01 0x00 0x00 0x00 0x21 and the rest are
all zeroes. The reply is one UDP packet as defined in the candm.h
file, struct CMD_reply with struct RPY_Tracking as data.
