157 * Function to parse a path and turn it into components
159 * The general format of an SMB URI is explain in Christopher Hertel's CIFS
160 * book, at http://ubiqx.org/cifs/Appendix-D.html. We accept a subset of the
161 * general format ("smb:" only; we do not look for "cifs:"), and expand on
162 * what he calls "context", herein called "options" to avoid conflict with the
163 * SMBCCTX context used throughout this library. We add the "mb" keyword
164 * which applies as follows:
168 * smb://[[[domain;]user[:password@]]server[/share[/path[/file]]]][?options]
172 * smb:// show all workgroups known by the first master browser found
173 * smb://?mb=.any same as smb:// (i.e. without any options)
175 * smb://?mb=.all show all workgroups known by every master browser found.
176 * Why might you want this? In an "appliance" application
177 * where the workgroup/domain being used on the local network
178 * is not known ahead of time, but where one wanted to
179 * provide network services via samba, a unique workgroup
180 * could be used. However, when the appliance is first
181 * started, the local samba instance's master browser has not
182 * synchronized with the other master browser(s) on the
183 * network (and might not synchronize for 12 minutes) and
184 * therefore is not aware of the workgroup/ domain names
185 * available on the network. This option may be used to
186 * overcome the problem of a libsmbclient application
187 * arbitrarily selecting the local (still ignorant) master
188 * browser to obtain its list of workgroups/domains and
189 * getting back a practically emmpty list. By requesting
190 * the list of workgroups/domains from each found master
191 * browser on the local network, a complete list of
192 * workgroups/domains can be built.
194 * smb://?mb=name NOT YET IMPLEMENTED -- show all workgroups known by the
195 * master browser whose name is "name"
197 * smb://name/ if name<1D> or name<1B> exists, list servers in
198 * workgroup, else, if name<20> exists, list all shares
201 * If "options" are provided, this function returns the entire option list as
202 * a string, for later parsing by the caller.
