Description

The zdir_patch class works with one patch, which says "create this file" or "delete this file" (referring to a zfile item each time).

Example

From zdir_patch_test method

 zfile_t *file = zfile_new (".", "bilbo");
 zdir_patch_t *patch = zdir_patch_new (".", file, patch_create, "/");
 zfile_destroy (&file);

 file = zdir_patch_file (patch);
 assert (streq (zfile_filename (file, "."), "bilbo"));
 assert (streq (zdir_patch_vpath (patch), "/bilbo"));  zdir_patch_destroy (&patch);
