tls_deinit() function

tls_deinit - Deinitialize TLS library @tls_ctx: TLS context data from tls_init() Called once during program shutdown and once for each RSN pre-authentication session. If global library deinitialization is needed (i.e., one that is shared between both authentication types), the TLS library wrapper should maintain a reference counter and do global deinitialization only when moving from 1 to 0 references.
