Basically, it is now no longer the case 957c478bd9Sstevel@tonic-gate * that an entry in a directory (as described by the 'pcdir' structure above) 967c478bd9Sstevel@tonic-gate * contains the entire name of a file. Now, a directory entry can consist of 977c478bd9Sstevel@tonic-gate * a long filename component (a series of 'pcdir'-like structures) followed 987c478bd9Sstevel@tonic-gate * by a short filename (the old form). Each long filename component is 997c478bd9Sstevel@tonic-gate * identified by having it's Read-Only, Hidden, System, and Volume Label 1007c478bd9Sstevel@tonic-gate * attributes set. Each can store 13 Unicode characters (16-bits, of 1017c478bd9Sstevel@tonic-gate * which we only look at the lower 8 for now), broken into (gak) three 1027c478bd9Sstevel@tonic-gate * sections of the entry (since that's the way the available bits fall out). 1037c478bd9Sstevel@tonic-gate * In addition, each long filename entry has a sequence number (starting 1047c478bd9Sstevel@tonic-gate * from 1). The first entry has bit 7 (0x40) set in the sequence number, and 1057c478bd9Sstevel@tonic-gate * has the maximum value in the sequence. This may seem a bit backwards, and 1067c478bd9Sstevel@tonic-gate * it gets worse: the first entry stores the last component of 1077c478bd9Sstevel@tonic-gate * the name. So the directory entry for a file named 1087c478bd9Sstevel@tonic-gate * "This is a very long filename indeed" might look like this: 1097c478bd9Sstevel@tonic-gate * 1107c478bd9Sstevel@tonic-gate * Offset Sequence Component Attributes Cluster Size 1117c478bd9Sstevel@tonic-gate * 0 0x43 "me indeed" RSHV 0 0 1127c478bd9Sstevel@tonic-gate * 32 0x02 "y long filena" RSHV 0 0 1137c478bd9Sstevel@tonic-gate * 64 0x01 "This is a ver" RSHV 0 0 1147c478bd9Sstevel@tonic-gate * 96 ---- "THISIS~1.TXT" <whatever> 2122 110 1157c478bd9Sstevel@tonic-gate * 1167c478bd9Sstevel@tonic-gate * The last entry is for the short filename, which stores actual information 1177c478bd9Sstevel@tonic-gate * about the file (like type, permissions, cluster, and size). The short name 1187c478bd9Sstevel@tonic-gate * is also used by non-long-filename aware applications (like Windows 3.X and 1197c478bd9Sstevel@tonic-gate * DOS). This name is generated by Windows 95 (and now Solaris) from the 1207c478bd9Sstevel@tonic-gate * long name, and must (of course) be unique within the directory. 1217c478bd9Sstevel@tonic-gate * Solaris continues to this entry to actually identify the file and its 1227c478bd9Sstevel@tonic-gate * attributes (filenames only really matter when names are used, like at 1237c478bd9Sstevel@tonic-gate * lookup/readdir/remove/create/rename time - for general access to the file 1247c478bd9Sstevel@tonic-gate * they aren't used). 1257c478bd9Sstevel@tonic-gate * 1267c478bd9Sstevel@tonic-gate * Long filenames can also be broken by applications that don't 1277c478bd9Sstevel@tonic-gate * understand them (for example, a Solaris 2.5.1 user could rename 1287c478bd9Sstevel@tonic-gate * "THISIS~1.TXT" to "test.exe"). This can be detected because each long 1297c478bd9Sstevel@tonic-gate * filename component has a checksum which is based on the short filename. 1307c478bd9Sstevel@tonic-gate * After reading the long filename entry, if the checksum doesn't match the 1317c478bd9Sstevel@tonic-gate * short name that follows, we simply ignore it and use the short name. 1327c478bd9Sstevel@tonic-gate * 1337c478bd9Sstevel@tonic-gate * One subtle thing - though long file names are case-sensitive, 1347c478bd9Sstevel@tonic-gate * searches for them are not. 1357c478bd9Sstevel@tonic-gate * 1367c478bd9Sstevel@tonic-gate * Another _very_ subtle thing. The number of characters in the 1377c478bd9Sstevel@tonic-gate * last long filename chunk (the first entry, with the 0x40 bit set) is 1387c478bd9Sstevel@tonic-gate * either all the characters (if there is no null, '\0'), or all the 1397c478bd9Sstevel@tonic-gate * characters up to the null. _However_, if the remaining characters are 1407c478bd9Sstevel@tonic-gate * null, Norton Disk Doctor and Microsoft ScanDisk will claim 1417c478bd9Sstevel@tonic-gate * that the filename entry is damaged. The remaining bytes must actually 1427c478bd9Sstevel@tonic-gate * contain 0xff (discovered with Disk Doctor). 1437c478bd9Sstevel@tonic-gate * 1447c478bd9Sstevel@tonic-gate * Some information about long filename support can be found in the 1457c478bd9Sstevel@tonic-gate * book "Inside Windows 95" by Adrian King. 1467c478bd9Sstevel@tonic-gate */ 1477c478bd9Sstevel@tonic-gate 1487c478bd9Sstevel@tonic-gate /* 1497c478bd9Sstevel@tonic-gate * The number of bytes in each section of the name in a long filename 1507c478bd9Sstevel@tonic-gate * entry.
