- /* getsearch -- ask user for string in table
- *
- * Usage: i = getsearch (prompt,table,defalt)
- * int i;
- * char *prompt, **table, *defalt;
- *
- * Getsearch prints the messge: prompt [defalt]
- * and asks the user to type in a line. This input text
- * is compared to all the strings in the table to see which
- * (if any) it matches; the stabsearch() routine is used
- * for the matching. If the string is ambiguous or invalid
- * (i.e. matches zero strings, or more than one), the cycle
- * is repeated. When a valid string is typed, the index
- * of the string it matches is returned. If the user just
- * types carriage return, the default string is used for matching.
- * The default value is also used on error or EOF in standard input.
- * The string table may be declared in this way:
- * char *table[] = {"string1","string2",...,0};
- *
- * HISTORY
- * $Log: getsearch.c,v $
- * Revision 1.2 90/12/11 17:55:23 mja
- * Add copyright/disclaimer for distribution.
- *
- * 28-Apr-85 Steven Shafer (sas) at Carnegie-Mellon University
- * Modified for 4.2 BSD. Now uses stderr for output.
- *
- * 23-Oct-82 Steven Shafer (sas) at Carnegie-Mellon University
- * Added code to use default value on EOF or error in standard input.
- *
- * 23-Jan-80 Steven Shafer (sas) at Carnegie-Mellon University
- * Created. This is just an alternative to getstab, but with funny
- * heuristic string-matching and the nifty "May I suggest..." stuff.
