+ *
+ * Meaning of URLs:
+ *
+ * smb://           Show all workgroups.
+ *
+ *                  The method of locating the list of workgroups varies
+ *                  depending upon the setting of the context variable
+ *                  context->options.browse_max_lmb_count.  This value
+ *                  determines the maximum number of local master browsers to
+ *                  query for the list of workgroups.  In order to ensure that
+ *                  a complete list of workgroups is obtained, all master
+ *                  browsers must be queried, but if there are many
+ *                  workgroups, the time spent querying can begin to add up.
+ *                  For small networks (not many workgroups), it is suggested
+ *                  that this variable be set to 0, indicating query all local
+ *                  master browsers.  When the network has many workgroups, a
+ *                  reasonable setting for this variable might be around 3.
+ *
+ * smb://name/      if name<1D> or name<1B> exists, list servers in

+ *                  for server ...

+/**
+ * Initialize for an arbitrary thread implementation. The caller should
+ * provide, as parameters, pointers to functions to implement the requisite
+ * low-level thread functionality. A function must be provided for each
+ * parameter; none may be null.
+ *
+ * If the thread implementation is POSIX Threads (pthreads), then the much
+ * simpler smbc_thread_pthread() function may be used instead of this one.
+ *
+ * @param create_mutex
+ *   Create a mutex. This function should expect three parameters: lockname,
+ *   pplock, and location. It should create a unique mutex for each unique
+ *   lockname it is provided, and return the mutex identifier in *pplock. The
+ *   location parameter can be used for debugging, as it contains the
+ *   compiler-provided __location__ of the call.
+ *
+ * @param destroy_mutex
+ *   Destroy a mutex. This function should expect two parameters: plock and
+ *   location. It should destroy the mutex associated with the identifier
+ *   plock. The location parameter can be used for debugging, as it contains
+ *   the compiler-provided __location__ of the call.
+ *
+ * @param lock_mutex
+ *   Lock a mutex. This function should expect three parameters: plock,
+ *   lock_type, and location. The mutex associated with identifier plock
+ *   should be locked if lock_type is 1, and unlocked if lock_type is 2. The
+ *   location parameter can be used for debugging, as it contains the
+ *   compiler-provided __location__ of the call.
+ *
+ * @param create_tls
+ *   Create thread local storage. This function should expect three
+ *   parameters: keyname, ppkey, and location. It should allocate an
+ *   implementation-specific amount of memory and assign the pointer to that
+ *   allocated memory to *ppkey. The location parameter can be used for
+ *   debugging, as it contains the compiler-provided __location__ of the
+ *   call. This function should return 0 upon success, non-zero upon failure.
+ *
+ * @param destroy_tls
+ *   Destroy thread local storage. This function should expect two parameters:
+ *   ppkey and location. The ppkey parameter points to a variable containing a
+ *   thread local storage key previously provided by the create_tls
+ *   function. The location parameter can be used for debugging, as it
+ *   contains the compiler-provided __location__ of the call.
+ *
+ * @param set_tls
+ *   Set a thread local storage variable's value. This function should expect
+ *   three parameters: pkey, pval, and location. The pkey parameter is a
+ *   thread local storage key previously provided by the create_tls
+ *   function. The (void *) pval parameter contains the value to be placed in
+ *   the thread local storage variable identified by pkey. The location
+ *   parameter can be used for debugging, as it contains the compiler-provided
+ *   __location__ of the call. This function should return 0 upon success;
+ *   non-zero otherwise.
+ *
+ * @param get_tls
+ *   Retrieve a thread local storage variable's value. This function should
+ *   expect two parameters: pkey and location. The pkey parameter is a thread
+ *   local storage key previously provided by the create_tls function, and
+ *   which has previously been used in a call to the set_tls function to
+ *   initialize a thread local storage variable. The location parameter can be
+ *   used for debugging, as it contains the compiler-provided __location__ of
+ *   the call. This function should return the (void *) value stored in the
+ *   variable identified by pkey.
