/* Filenames
 *
 * From a DIRITEM, you can query either the relative or the full name.
 *
 * The relative name does not include the tree root that was originally
 * passed to dir_buildlist. The full name does include this. Note however
 * that if you passed a relative name to dir_buildlist, the full
 * name you get back will not be an *absolute* pathname.
 *
 * Thus, if you call dir_buildlist with "c:\",
 * we will return:
 *      relative name:  ".\config.sys"
 *      full name:      "c:\config.sys"
 *
 * If you call dir_buildlist with ".\geraintd",
 * we will return:
 *      relative name:  ".\source\scandir.h"
 *      full name:      ".\geraintd\source\scandir.h"
 *
 * In both cases, we return a pointer to a filename string: you must
 * call dir_freefullname or dir_freerelname to free this memory when you
 * have finished with it. Depending on the implementation, one or other
 * (or possibly both) of these names will have been built specially
 * when you called the query function.
 *
 * You can also return a pointer to the tree root name. (In the above
 * examples this would be c:\ and .\geraintd). Depending on the implementation,
 * this may have been forced to an absolute path.
