Nearly all functions return a \fBmemcached_return_t\fP value.
This value can be translated to a printable string with memcached_strerror(3).

-Partitioning based on keys is testsed in the library. Using the key partioning
-functions it is possible to group sets of object onto servers.
+Objects are stored on servers by hashing keys. The hash value maps the key to a particular server. All clients understand how this hashing works, so it is possibly to reliably both push data to a server and retrieve data from a server.
+.sp
+Group keys can be optionally used to group sets of objects with servers.
+.sp
+Namespaces are supported, and can be used to partition caches so that multiple applications can use the same memcached servers.

\fBmemcached_st\fP structures are thread\-safe, but each thread must
contain its own structure (that is, if you want to share these among
