\fBlibmemcached\fP is a small, thread\-safe client library for the
-memcached protocol. The code has all been written with an eye to allow
+memcached protocol. The code has all been written to allow
for both web and embedded usage. It handles the work behind routing
-particular keys to specific servers that you specify (and values are
-matched based on server order as supplied by you). It implements both
-a modula and consistent method of object distribution.
+individual keys to specific servers specified by the developer (and values are
+matched based on server order as supplied by the user). It implements
+a modular and consistent method of object distribution.
.sp
There are multiple implemented routing and hashing methods. See the
-memcached_behavior_set() manpage.
+\fBmemcached_behavior_set()\fP manpage for more information.
.sp
All operations are performed against a \fBmemcached_st\fP structure.
These structures can either be dynamically allocated or statically
-allocated and then initialized by memcached_create(). Functions have been
-written in order to encapsulate the \fBmemcached_st\fP. It is not
+allocated and then initialized by \fBmemcached_create()\fP. Functions have
+been written in order to encapsulate the \fBmemcached_st\fP. It is not
recommended that you operate directly against the structure.
.sp
Nearly all functions return a \fBmemcached_return_t\fP value.
-This value can be translated to a printable string with memcached_strerror(3).
+This value can be translated to a printable string with
+\fBmemcached_strerror\fP.
.sp
Objects are stored on servers by hashing keys. The hash value maps the key to a particular server. All clients understand how this hashing works, so it is possibly to reliably both push data to a server and retrieve data from a server.

.SH CONSTANTS
.INDENT 0.0
.TP
.B MEMCACHED_DEFAULT_PORT
-.
The default port used by memcached(3).
.UNINDENT
.INDENT 0.0

This is the "stride" used in the consistent hash used between replicas.
.UNINDENT
.INDENT 0.0

.B MEMCACHED_MAX_HOST_LENGTH
-.
Maximum allowed size of the hostname.
.UNINDENT

.SH THREADS AND PROCESSES
.sp
-When using threads or forked processes it is important to keep an instance
-of \fBmemcached_st\fP per process or thread. Without creating your own locking
-structures you can not share a single \fBmemcached_st\fP. You can though call
-memcached_quit(3) on a \fBmemcached_st\fP and then use the resulting cloned
-structure.
