Each read operation 1887f667e74Sjose borrego * provides the caller with a structure containing information pertaining 1897f667e74Sjose borrego * to the next directory entry that matches the search criteria, namely 1907f667e74Sjose borrego * the filename or match pattern and, in the case of smb_odir_read_fileinfo(), 1917f667e74Sjose borrego * the search attributes. 1927f667e74Sjose borrego * 1937f667e74Sjose borrego * The odir maintains a buffer (d_buf) of directory entries read from 1947f667e74Sjose borrego * the filesystem via a vop_readdir. The buffer is populated when a read 1957f667e74Sjose borrego * request (smb_odir_next_odirent) finds that the buffer is empty or that 1967f667e74Sjose borrego * the end of the buffer has been reached, and also when a new client request 1977f667e74Sjose borrego * (find next) begins. 1987f667e74Sjose borrego * 1997f667e74Sjose borrego * The data in d_buf (that which is returned from the file system) can 2007f667e74Sjose borrego * be in one of two formats. If the file system supports extended directory 2017f667e74Sjose borrego * entries we request that the data be returned as edirent_t structures. If 2027f667e74Sjose borrego * it does not the data will be returned as dirent64_t structures. For 2037f667e74Sjose borrego * convenience, when the next directory entry is read from d_buf by 2047f667e74Sjose borrego * smb_odir_next_odirent it is translated into an smb_odirent_t. 2057f667e74Sjose borrego * 2067f667e74Sjose borrego * smb_odir_read_fileinfo 2077f667e74Sjose borrego * The processing required to obtain the information to populate the caller's 2087f667e74Sjose borrego * smb_fileinfo_t differs depending upon whether the directory search is for a 2097f667e74Sjose borrego * single specified filename or for multiple files matching a search pattern. 2107f667e74Sjose borrego * Thus smb_odir_read_fileinfo uses two static functions: 2117f667e74Sjose borrego * smb_odir_single_fileinfo - obtains the smb_fileinfo_t info for the single 2127f667e74Sjose borrego * filename as specified in smb_odir_open request. 2137f667e74Sjose borrego * smb_odir_wildcard_fileinfo - obtains the smb_fileinfo_t info for the filename 2147f667e74Sjose borrego * returned from the smb_odir_next_odirent. This is called in a loop until 2157f667e74Sjose borrego * an entry matching the search criteria is found or no more entries exist. 2167f667e74Sjose borrego * 2177f667e74Sjose borrego * If a directory entry is a VLNK, the name returned in the smb_fileinfo_t 2187f667e74Sjose borrego * is the name of the directory entry but the attributes are the attribites 2197f667e74Sjose borrego * of the file that is the target of the link. If the link target cannot 2207f667e74Sjose borrego * be found the attributes returned are the attributes of the link itself. 2217f667e74Sjose borrego * 222037cac00Sjoyce mcintosh * smb_odir_read_streaminfo 2237f667e74Sjose borrego * In order for an odir to provide information about stream files it 2247f667e74Sjose borrego * must be opened with smb_odir_openat(). smb_odir_read_streaminfo() can 2257f667e74Sjose borrego * then be used to obtain the name and size of named stream files. 2267f667e74Sjose borrego * 2277f667e74Sjose borrego * Resuming a Search 2287f667e74Sjose borrego * ----------------- 2297f667e74Sjose borrego * A directory search often consists of multiple client requests: an initial 2307f667e74Sjose borrego * find_first request followed by zero or more find_next requests and a 2317f667e74Sjose borrego * find_close request. 2327f667e74Sjose borrego * The find_first request will open and lookup the odir, read its desired 2337f667e74Sjose borrego * number of entries from the odir, then release the odir and return. 2347f667e74Sjose borrego * A find_next request will lookup the odir and read its desired number of 2357f667e74Sjose borrego * entries from the odir, then release the odir and return. 2367f667e74Sjose borrego * At the end of the search the find_close request will close the odir. 2377f667e74Sjose borrego * 2387f667e74Sjose borrego * In order to be able to resume a directory search (find_next) the odir 2397f667e74Sjose borrego * provides the capability for the caller to save one or more resume points 2407f667e74Sjose borrego * (cookies) at the end of a request, and to specify which resume point 2417f667e74Sjose borrego * (cookie) to restart from at the beginning of the next search. 2427f667e74Sjose borrego * smb_odir_save_cookie(..., cookie) 2437f667e74Sjose borrego * smb_odir_resume_at(smb_odir_resume_t *resume) 2447f667e74Sjose borrego * A search can be resumed at a specified resume point (cookie), the resume 2457f667e74Sjose borrego * point (cookie) stored at a specified index in the d_cookies array, or 2467f667e74Sjose borrego * a specified filename.
