  74 .SH DESCRIPTION
  75 .sp
  76 \fBlibmemcached\fP performs operations on a list of hosts. The order of
  77 these hosts determine routing to keys. Functions are provided to add keys to
  78 memcached_st structures. To manipulate lists of servers see
  79 memcached_server_st(3).
  80 .sp
  81 \fI\%memcached_server_count()\fP provides you a count of the current number of
  82 servers being used by a \fBmemcached_st\fP structure.
  83 .INDENT 0.0
  84 .TP
  85 .B \fI\%memcached_server_add()\fP pushes a single TCP server into the \fBmemcached_st\fP structure. This server will be placed at the end. Duplicate servers
  86 .sp
  87 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.
  88 .UNINDENT
  89 .sp
  90 \fI\%memcached_server_add_udp()\fP pushes a single UDP server into the \fBmemcached_st\fP structure. This server will be placed at the end. Duplicate
  91 servers are allowed, so duplication is not checked. Executing this function with out setting the \fBMEMCACHED_BEHAVIOR_USE_UDP\fP behavior will result in a
  92 \fBMEMCACHED_INVALID_HOST_PROTOCOL\fP.
  93 .sp
  94 \fI\%memcached_server_add_unix_socket()\fP pushes a single UNIX socket into the \fBmemcached_st\fP structure. This UNIX socket will be placed at the end.
  95 Duplicate servers are allowed, so duplication is not checked. The length
  96 of the filename must be one character less than \fBMEMCACHED_MAX_HOST_LENGTH\fP.
  97 .sp
  98 \fI\%memcached_server_push()\fP pushes an array of \fBmemcached_server_st\fP into the \fBmemcached_st\fP structure. These servers will be placed at
  99 the end. Duplicate servers are allowed, so duplication is not checked. A
 100 copy is made of structure so the list provided (and any operations on
 101 the list) are not saved.
 102 .sp
 103 \fI\%memcached_server_by_key()\fP allows you to provide a key and retrieve the
 104 server which would be used for assignment. This structure is cloned
 105 from its original structure and must be freed. If NULL is returned you
 106 should consult *error. The returning structure should be freed with
 107 \fBmemcached_server_free()\fP.
 108 .sp
 109 \fI\%memcached_server_get_last_disconnect()\fP returns a pointer to the last
 110 server for which there was a connection problem. It does not mean this
 111 particular server is currently dead but if the library is reporting a server
 112 is, the returned server is a very good candidate.
 113 .sp
 114 \fI\%memcached_server_cursor()\fP takes a memcached_st and loops through the
 115 list of hosts currently in the cursor calling the list of callback
 116 functions provided. You can optionally pass in a value via
 117 context which will be provided to each callback function. An error
 118 return from any callback will terminate the loop. \fI\%memcached_server_cursor()\fP is passed the original caller \fBmemcached_st\fP in its current state.
