You need to use whatever mechanism is normal in your threading environment of choice to generate a unique consistent identifier for a thread. If you don't know what that is, the place to ask is a list or group which discusses that environment's threading facilities. OpenSSL doesn't know or care what mechanism is used - that's why it's left to the user to provide it. Many environments provide a function call which returns a thread identifier. In those that don't, you can probably do something with thread-private data facilities. Many programs need an identifier of this sort, so I expect most threading support libraries will have some way to create one. Experienced users of the environment should be able to advise on a commonly-used method. ______________________________________________________________________ OpenSSL Project http://www.openssl.org User Support Mailing List openssl-users@openssl.org Automated List Manager [EMAIL PROTECTED]
