[osip-dev] alloc and free of dnsutils_list

[FEICHTER Christoph]

hi,

 

I have a question regarding dnsutils_list.

this variable is allocated on the first use, and all

eXosip instances share the same dnsutils_list. 

but it is never freed – that’s an unclean memory handling.

 

I guess there are 2 possible solutions:

1. dnsutils_list remains static – to be used by all instances
   then we need a counter for the number of instances (incremented in eXosip_initialize, decremented in eXosip_quit).
   additionally you would require a mutex to synchronize
   when eXosip_initialize and eXosip_quit are called from various threads.
   
2. every eXosip instance gets its own dnsutils_list.
   then we don’t need the conter and synchronization – but the instances
   don’t share a common dnsutils-list.

 

which solution would you prefer ?

 

br,

Christoph
