json_object_set_new

[sthu...@gmail.com]

I am using json_object_set_new() api to set a large string (of approx 2K) to an object using json_string().

n = json_object_set_new(sdp, "addr", json_string(addr_buf));

However, this api is returning -1. How do I debug this and under what conditions does the API return failure?

Thanks.

In your case, json_object_set_new() returns -1 if:

- sdp is not an object

- json_string(addr_buf) returns NULL

- memory allocation fails when allocating space for the internal
structures of the hash table

json_string(addr_buf) returs NULL if:

- addr_buf is NULL or not valid UTF-8

- memory allocation fails

Indeed json_string() is returning NULL and the cause seems to be invalid UTF-8 (because addr_buf is not NULL). Any pointers on how to validate that it is a proper UTF-8 string? because content seems to be harmless and contains pure ascii text.

I was able to find the issue with the string and fixed it. Thanks for clarifications.
