| 5 | * Revision 1.1.1.1 2003/11/04 23:34:57 mjames |
||
| 6 | * Imported into local repositrory |
||
| 7 | * |
||
| 8 | * Revision 1.9 2002/01/16 11:22:49 mjames |
||
| 9 | * database.h header file is read in first as it undefined DLL stuff irrelevant |
||
| 10 | * to HPUX |
||
| 11 | * |
||
| 12 | * Revision 1.8 2002/01/15 12:33:14 mjames |
||
| 13 | * removed unused variable |
||
| 14 | * |
||
| 15 | * Revision 1.7 2001/10/31 22:20:18 mjames |
||
| 16 | * Tidying up problematical comments caused by CVS |
||
| 17 | * 'intelligent' comment guessing |
||
| 18 | * |
||
| 19 | * Revision 1.6 2001/10/31 16:18:04 mjames |
||
| 20 | * Added a datastructure to hide regular expression information from programs. |
||
| 21 | * Changed call to regexec to indicate 0 subexpressions to be matched |
||
| 22 | * rather than a number dependent on strlen(string) which was wrong. |
||
| 23 | * |
||
| 24 | * Revision 1.5 2001/10/10 20:18:20 mjames |
||
| 25 | * Added a vert_regcomp function to compile regular expressions |
||
| 26 | * with '^' (match start string) and '$' (match end string) bracketing |
||
| 27 | * this => wildcard must match entire string not just a part of it. |
||
| 28 | * |
||
| 29 | * Revision 1.4 2001/10/07 20:50:51 mjames |
||
| 30 | * Added wildcard checking (warn user about |
||
| 31 | * using wildcard '*' on the end of a string in stead of wildcard '.*') |
||
| 32 | * |
||
| 33 | * Revision 1.3 2001/09/25 23:15:22 mjames |
||
| 34 | * Converted wildcards to use proper regexp pattern match library |
||
| 35 | * |

||
| 45 | * until a constant is located |
