Thread Safety

RHT replicas are inherently thread-safe and no thread synchronization is necessary to legally call the Dictionary Operation functions on a replica.

rht_lib_init must be successfully called by a single thread before any other RHT functions are called. Upon initialization, RHT library will spawn a thread to monitor network communication. Therefore the RHT library must be linked into a program that supports threading.

rht_strerror is inherently thread safe.

Locks on the replica are automatically grabbed and dropped upon entry and exit as necessary.

rht_pair, rht_snap and rht_nset are read only structures, so only the reclamation of these structures must be synchronized with operations and must be done only once per structure instantiation. (you don't need to reclaim a rht_nset; see on_synch_diff_cb).

A properly initialized rht_it references an underlying constant rht_pair. Otherwise, access to the iterator itself is not synchronized.
