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
68 \fI\%memcached_create()\fP.
69 .sp
70 \fI\%memcached_clone()\fP is similar to \fI\%memcached_create()\fP but
71 it copies the defaults and list of servers from the source
72 \fI\%memcached_st\fP. If you pass a null as the argument for the source
73 to clone, it is the same as a call to \fI\%memcached_create()\fP.
74 If the destination argument is NULL a \fI\%memcached_st\fP will be allocated
75 for you.
76 .sp
77 \fI\%memcached_servers_reset()\fP allows you to zero out the list of
78 servers that the \fI\%memcached_st\fP has.
79 .sp
80 To clean up memory associated with a \fI\%memcached_st\fP structure you
81 should pass it to \fI\%memcached_free()\fP when you are finished using it.
82 \fI\%memcached_free()\fP is the only way to make sure all memory is
83 deallocated when you finish using the structure.
84 .sp
85 You may wish to avoid using memcached_create(3) or memcached_clone(3) with a
86 stack based allocation. The most common issues related to ABI safety involve
87 heap allocated structures.
88 .SH RETURN
89 .sp
90 \fI\%memcached_create()\fP returns a pointer to the \fI\%memcached_st\fP
91 that was created (or initialized). On an allocation failure, it returns NULL.
92 .sp
93 \fI\%memcached_clone()\fP returns a pointer to the \fI\%memcached_st\fP
94 that was created (or initialized). On an allocation failure, it returns NULL.
