-memcached_server_add() pushes a single TCP server into the \fBmemcached_st\fPstructure. This server will be placed at the end. Duplicate servers are
-allowed, so duplication is not checked. Executing this function with the
-\fBMEMCACHED_BEHAVIOR_USE_UDP\fP behavior set will result in a
-\fBMEMCACHED_INVALID_HOST_PROTOCOL\fP.
