245 *
246 * smb:// Show all workgroups.
247 *
248 * The method of locating the list of workgroups varies
249 * depending upon the setting of the context variable
250 * context->options.browse_max_lmb_count. This value
251 * determine the maximum number of local master browsers to
252 * query for the list of workgroups. In order to ensure that
253 * a complete list of workgroups is obtained, all master
254 * browsers must be queried, but if there are many
255 * workgroups, the time spent querying can begin to add up.
256 * For small networks (not many workgroups), it is suggested
257 * that this variable be set to 0, indicating query all local
258 * master browsers. When the network has many workgroups, a
259 * reasonable setting for this variable might be around 3.

261 * smb://name/ if name<1D> or name<1B> exists, list servers in
262 * workgroup, else, if name<20> exists, list all shares
263 * for server ...

266 * string, for later parsing by the caller. Note that currently, no options
