[openssl-users] Replacing CRYPTO_NUM_LOCKS on migration 101 to 110

[Paul Dale]

OpenSSL 1.1.x handle the locking themselves.  You don't need to install the locking call backs and don't need to provide locking functionality.

Subject: [openssl-users] Replacing CRYPTO_NUM_LOCKS on migration 101 to 110

 

I am migrating a multi-threaded Windows application from OpenSSL 1.0.1h to 1.1.0f.

 

I am using the Shining Light pre-built Windows DLLs.

 

The code, which I wrote some time ago, has a statement HANDLE Comm::sslMutexArray[CRYPTO_NUM_LOCKS];        

 

The array is referenced by my sslLockingFunction.

 

When I compile with the 1.1.0f headers I get at undefined symbol on CRYPTO_NUM_LOCKS.

 

Is my understanding of http://www.manpagez.com/man/3/CRYPTO_num_locks/osx-10.3.php correct? Basically, I need to replace the static array sslMutexArray[CRYPTO_NUM_LOCKS] with a malloc() or new to get an array of the size returned by a call to CRYPTO_num_locks(void)? Is that correct? Anything else I need to do in this regard?

 

Thanks,

 

Charles
