The question: if I provide locking_callback, will it be called only from the threads where I invoke OpenSSL functions, or OpenSSL may call it from some private/internal threads not created by me?
Since there's no callback to create a thread, OpenSSL has no way to create a thread.
I assume OpenSSL does not invoke the callback from any "not-mine" threads, because the documentation says I should only provide the callback if *my* program is multi-threaded, from which I deduce there is no any concurrency inside OpenSSL, until I invoke it from several threads. But I would like to here a confirmation.
If OpenSSL created its own threads, that would defeat the entire logic of the threading callbacks. The idea is to be able to compile OpenSSL once and use it with various different threading models.
