Is there a way to append to file?

[bhavyanshu]

The default json_object_to_file only writes to the file. I can't find anything related to appending to file. Why not let us open file using fopen in append mode and just provide a function json_object_to_file accepting file pointer as argument or something like that or just provide an optional argument for specifying file modes. Any way would be good.

This would be very good for logging as JSON, particularly if using the likes of logstash, with its 'jsonlines' input module. This is a requirement for a project I'm working on.
