[ldns-users] Is ldns C library thread-safe?

[Willem Toorop]

Yes,

ldns is thread-safe in the sense that it doesn't use global variables.
It does use libcrypto for cryptographic operations which might not be
thread safe.  You have to check with the OpenSSL that you are using on
how to make sure they can be used thread-safe.

Here are some pointers:
