  58 .SH DESCRIPTION
  59 .sp
  60 \fI\%memcached_create()\fP is used to create a \fI\%memcached_st\fP
  61 structure that will then be used by other libmemcached(3) functions to
  62 communicate with the server. You should either pass a statically declared
  63 \fI\%memcached_st\fP to \fI\%memcached_create()\fP or
  64 a NULL. If a NULL passed in then a structure is allocated for you.
  65 .sp
  66 Please note, when you write new application use
  67 \fBmemcached()\fP over \fI\%memcached_create()\fP.
  68 .sp
  69 \fI\%memcached_clone()\fP is similar to \fI\%memcached_create()\fP but
  70 it copies the defaults and list of servers from the source
  71 \fI\%memcached_st\fP. If you pass a null as the argument for the source
  72 to clone, it is the same as a call to \fI\%memcached_create()\fP.
  73 If the destination argument is NULL a \fI\%memcached_st\fP will be allocated
  74 for you.
  75 .sp
  76 \fI\%memcached_servers_reset()\fP allows you to zero out the list of
  77 servers that the \fI\%memcached_st\fP has.
  78 .sp
  79 To clean up memory associated with a \fI\%memcached_st\fP structure you
  80 should pass it to \fI\%memcached_free()\fP when you are finished using it.
  81 \fI\%memcached_free()\fP is the only way to make sure all memory is
  82 deallocated when you finish using the structure.
  83 .sp
  84 You may wish to avoid using memcached_create(3) or memcached_clone(3) with a
  85 stack based allocation. The most common issues related to ABI safety involve
  86 heap allocated structures.
  87 .SH RETURN
  88 .sp
  89 \fI\%memcached_create()\fP returns a pointer to the \fI\%memcached_st\fP
  90 that was created (or initialized). On an allocation failure, it returns NULL.
  91 .sp
  92 \fI\%memcached_clone()\fP returns a pointer to the \fI\%memcached_st\fP
  93 that was created (or initialized). On an allocation failure, it returns NULL.
