- /* searcharg -- parse string from string table
- *
- * Usage: i = searcharg (ptr,brk,prompt,table,defalt);
- * int i;
- * char **ptr,*brk,*prompt,**table,*defalt;
- *
- * Searcharg parses an argument from the string pointed to by "ptr",
- * and bumps ptr to point to the next argument in the string.
- * The argument thus parsed is looked up in the string array
- * "table", and its index is returned. If the argument is ambiguous
- * or not found in the table, getsearch() is used to ask the user
- * for a string and look it up.
- * "Brk" is the list of characters which may terminate an argument;
- * if 0, then " " is used.
- *
- * The string table might be declared this way:
- * char *table[] {"one","two","three",0};
- * The last entry must be a zero.
