-\fIlibmemcached(3)\fP behavior can be modified by use memcached_behavior_set().
-Default behavior is the library strives to be quick and accurate. Some
-behavior, while being faster, can also result in not entirely accurate
-behavior (for instance, memcached_set() will always respond with
-\fBMEMCACHED_SUCCESS\fP).

-memcached_behavior_get() takes a behavior flag and returns whether or not
-that behavior is currently enabled in the client.

-memcached_behavior_set() changes the value of a particular option of the
-client. It takes both a flag (listed below) and a value. For simple on or
-off options you just need to pass in a value of 1. Calls to
-memcached_behavior_set() will flush and reset all connections.

.B MEMCACHED_BEHAVIOR_USE_UDP
Causes \fIlibmemcached(3)\fP to use the UDP transport when communicating
with a memcached server. Not all I/O operations are testsed
when this behavior is enababled. The following operations will return
-\fBMEMCACHED_NOT_SUPPORTED\fP when executed with the MEMCACHED_BEHAVIOR_USE_UDP
-enabled: memcached_version(), memcached_stat(), memcached_get(),
-memcached_get_by_key(), memcached_mget(), memcached_mget_by_key(),
-memcached_fetch(), memcached_fetch_result(), memcached_value_fetch().
+\fBMEMCACHED_NOT_SUPPORTED\fP when executed with the \fI\%MEMCACHED_BEHAVIOR_USE_UDP\fP enabled: \fBmemcached_version()\fP, \fBmemcached_stat()\fP, \fBmemcached_get()\fP, \fBmemcached_get_by_key()\fP, \fBmemcached_mget()\fP, \fBmemcached_mget_by_key()\fP, \fBmemcached_fetch()\fP, \fBmemcached_fetch_result()\fP, \fBmemcached_value_fetch()\fP.
.sp
All other operations are testsed but are executed in a \(aqfire\-and\-forget\(aq
mode, in which once the client has executed the operation, no attempt
will be made to ensure the operation has been received and acted on by the
server.
.sp
-\fIlibmemcached(3)\fP does not allow TCP and UDP servers to be shared within
-the same libmemached(3) client \(aqinstance\(aq. An attempt to add a TCP server
-when this behavior is enabled will result in a \fBMEMCACHED_INVALID_HOST_PROTOCOL\fP,
-as will attempting to add a UDP server when this behavior has not been enabled.
