These are spottily documented by * Microsoft. In their infinite stupidity, they completely ignored * the possibility of using an SUSP record with the long filename * in it, and instead wrote out a duplicate directory tree with the * long filenames in it. * * I am not sure why they did this. One reason is that they get the path * tables with the long filenames in them. * * There are two basic principles to Joliet, and the non-Unicode variant * known as Romeo. Long filenames seem to be the main one, and the second * is that the character set and a few other things is substantially relaxed. * * The SVD is identical to the PVD, except: * * Id is 2, not 1 (indicates SVD). * escape_sequences contains UCS-2 indicator (levels 1, 2 or 3). * The root directory record points to a different extent (with different * size). * There are different path tables for the two sets of directory trees. * * The following fields are recorded in Unicode: * system_id * volume_id * volume_set_id * publisher_id * preparer_id * application_id * copyright_file_id * abstract_file_id * bibliographic_file_id * * Unicode strings are always encoded in big-endian format. * * In a directory record, everything is the same as with iso9660, except * that the name is recorded in unicode. The name length is specified in * total bytes, not in number of unicode characters. * * The character set used for the names is different with UCS - the * restrictions are that the following are not allowed: * * Characters (00)(00) through (00)(1f) (control chars) * (00)(2a) '*' * (00)(2f) '/' * (00)(3a) ':' * (00)(3b) ';' * (00)(3f) '?' * (00)(5c) '\' */ #include "config.h" #include "mkisofs.h" #include "iso9660.h" #include #include static int jpath_table_index; static struct directory ** jpathlist; static int next_jpath_index = 1; static int sort_goof; static int generate_joliet_path_tables __PR((void)); static int DECL(joliet_sort_directory, (struct directory_entry ** sort_dir)); static void DECL(assign_joliet_directory_addresses, (struct directory * node)); static int jroot_gen __PR((void)); /* * Function: convert_to_unicode * * Purpose: Perform a 1/2 assed unicode conversion on a text * string. * * Notes: */ static void FDECL3(convert_to_unicode, unsigned char *, buffer, int, size, char *, source ) { unsigned char * tmpbuf; int i; int j; /* * If we get a NULL pointer for the source, it means we have an inplace * copy, and we need to make a temporary working copy first. */ if( source == NULL ) { tmpbuf = (u_char *) e_malloc(size); memcpy( tmpbuf, buffer, size); } else { tmpbuf = (u_char *)source; } /* * Now start copying characters.
