Hi,

We are using openssl 1.0.0d in our multi threaded application.
I would like to know when to set CRYPTO_set_locking_callback and when to set
CRYPTO_set_dynlock_* callbacks

The openssl document says that *dyn* call backs are required to improve
performance. From openssl code, it seems only e_chill engine is using them.
Pls correct if I am wrong here.

Is the application required to set all the callbacks or just
CRYPTO_set_locking_callback
and CRYPTO_THREADID_set_callback.

Also if *dyn* callbacks are set, does the application still need to set
CRYPTO_set_locking_callback and CRYPTO_THREADID_set_callback.

Thanks in advance,
Arun
