Revision history: 1.x [moved to History.510 for brevity] 2.0 Mandrichenko 7-apr-1993 Implement PKWARE style VMS file attributes 2.0-1 Mandrichenko 10-apr-1993 ACL handling code added. 2.1 Mandrichenko 24-aug-1993 Get both PKWARE and new INFO-ZIP signatures as equivalent Use vmsmunch.h instead of fatdef.h 2.2 Cave Newt 3-oct-1993 Merged GRR 5.1e changes with latest Igor version: open_outfile, close_outfile, check_for_newer, UpdateCRC, flush, no ZIPINFO, ctype.h, pInfo->textmode, etc. Also merged new do_wild/mapname/ checkdir routines from Igor and moved VMSmunch.h into vms.h. 2.2-1 Mandrichenko 14-dec-1993 Bug fixes in mapname/checkdir stuff. _flush_stream() rewritten to fix some bugs. 2.2-2 Goathunter 3 Jan 94 Fixes for Alpha-VMS. 2.2-3 Cave Newt 11 Jan 94 Disabled version-check by default; enable with CHECK_VERSIONS. Installed Igor's ctrl-Z patch. 2.2-4 Mandrichenko 18 Jan 94 Fixed auto-appending of ".zip" and inability to create second level of directory structure. 2.2-5 Cave Newt, Mike Freeman 28 Jan 94 Changed close_outfile() to return void for compatibility; fixed declaration of second parameter to flush() (ulg size); changed str[n]icmp() to STR[N]ICMP(). 2.2-6 Christian Spieler 9 Apr 94 Numerous bug fixes/improvements. 2.2-7 Cave Newt 11 Apr 94 Fixed version-number/semicolon bug. 2.3 Cave Newt 21 Jun 94 Added prototype version() routine. 2.3-1 Cave Newt 1 Jul 94 *Really* fixed version-number/semicolon bug. 2.3-2 Rodney Brown 10 Jul 94 Added VMS status/severity level (define RETURN_SEVERITY) 2.3-3 Charles Bailey 10 Aug 94 Fixed severity levels. 2.3-4 CN, CS, IM, RB 16 Aug 94 Further severity tweaks; do_wild() bugfix (CS) 2.3-5 CS, CN, IM, GH 18 Aug 94 Further do_wild() modifications and fixes. 2.3-6 Christian Spieler 23 Aug 94 Added lots of typecasts and fixed some initializations for DEC C. ---------------------------------------------------------------------------*/ #ifdef VMS /* VMS only ! */ #include "unzip.h" #include "vms.h" /* now includes VMSmunch.h */ #define BUFS512 8192*2 /* Must be a multiple of 512 */ #define OK(s) ((s)&1) /* VMS success or warning status */ #define STRICMP(s1,s2) STRNICMP(s1,s2,2147483647) /* * Local static storage */ static struct FAB fileblk; static struct XABDAT dattim; static struct XABRDT rdt; static struct RAB rab; static struct NAM nam; static struct FAB *outfab = 0; static struct RAB *outrab = 0; static struct XABFHC *xabfhc = 0; static struct XABDAT *xabdat = 0; static struct XABRDT *xabrdt = 0; static struct XABPRO *xabpro = 0; static struct XABKEY *xabkey = 0; static struct XABALL *xaball = 0; struct XAB *first_xab = 0L, *last_xab = 0L; static char query = 0; static int text_output = 0, raw_input, hostnum; static uch rfm; static uch locbuf[BUFS512]; static int loccnt = 0; static uch *locptr; static char got_eol = 0; static int _flush_blocks(), _flush_stream(), _flush_varlen(), _flush_qio(), _close_qio(), _close_rms(), WriteRecord(), WriteBuffer(), find_eol(); static int (*_flush_routine)(), (*_close_routine)(); static int get_vms_version(); static int replace(); static uch *extract_block(); static void init_buf_ring(); static void decompress_bits(); static void UpdateCRC(); static void message(); static void free_up(); struct bufdsc { struct bufdsc *next; uch *buf; int bufcnt; }; static struct bufdsc b1, b2, *curbuf; static uch buf1[BUFS512]; int check_format() { int rtype; struct FAB fab; fab = cc$rms_fab; fab.fab$l_fna = zipfn; fab.fab$b_fns = strlen(zipfn); sys$open(&fab); rtype = fab.fab$b_rfm; sys$close(&fab); if (rtype == FAB$C_VAR || rtype == FAB$C_VFC) { fprintf(stderr, "\n Error: zipfile is in variable-length record format.
