The thread_tls_id value is initialized once when pj_init() is called, when the pj_thread_init() function is called, and the value remains constant until pj_shutdown() is called. Subsequent thread creation will only associate thread specific data to this thread_tls_id index, and must not change the value of thread_tls_id itself. If thread_tls_id value is changed, things will break. Cheers Benny > -Gaurav > > -------------- next part -------------- An HTML attachment was scrubbed...
