JSON Library Overview

QNX SDP8.0JSON Library ReferenceAPIDeveloper

The JSON library, libjson, allows applications to decode and encode JSON data. This is useful for reading and interpreting complex data or transferring data between systems.

The two most common use cases are:

Reading JSON data files — Some applications use configuration data that's encoded in JSON. The library saves you from writing a parser to manually extract individual fields and copy them into data structures.
Sending and receiving protocol messages written in JSON — The QNX over the air (OTA) servers provide software updates to remote clients, using JSON-encoded data. If you have applications that need to send data to remote clients, you can use the library to encode multi-layered JSON data that you can then output to protocol messages.

Other possible use cases are if you want to read JSON data, modify the contents, and resave the data, or generate your own JSON data for internal use.
