How to free the memory created by map_json_to_struct in child thread

[bskrish757]

Hi,

Background:

I have a main thread that has to call map_json_to_struct and pass the resulting structure to a child thread (not calling map_json_to_struct inside the child thread to avoid using mutex because it will slow down my execution in case of a huge load), The converted structure is not used by any other thread including the main thread.

Issue:

Now the issue is, that whenever the child thread finishes execution, I get memory leaks for some memory created by map_json_to_struct in the main thread,

Ultimately I want to free the resource in the child thread itself(there will not be any synchronization issue as this mapped structure is not used by any other threads)
NOTE: My main thread cannot wait for the child thread to finish so i cannot use join call.

is there a way to handle this scenario?

Thanks in advance
