6 /* SUMMARY
7 /*	match a string against a pattern list
8 /* SYNOPSIS
9 /*	#include <string_list.h>
10 /*
11 /*	STRING_LIST *string_list_init(flags, pattern_list)
12 /*	int	flags;
13 /*	const char *pattern_list;
14 /*
15 /*	int	string_list_match(list, name)
16 /*	STRING_LIST *list;
17 /*	const char *name;
18 /*
19 /*	void string_list_free(list)
20 /*	STRING_LIST *list;
21 /* DESCRIPTION
22 /*	This is a convenience wrapper around the match_list module.
23 /*
24 /*	This module implements tests for list membership of a string.
25 /*
26 /*	Patterns are separated by whitespace and/or commas. A pattern
27 /*	is either a string, a file name (in which case the contents
28 /*	of the file are substituted for the file name) or a type:name
29 /*	lookup table specification.
30 /*
31 /*	A string matches a string list when it appears in the list of
32 /*	string patterns. The matching process is case insensitive.
33 /*	In order to reverse the result, precede a pattern with an
34 /*	exclamation point (!).
35 /*
36 /*	string_list_init() performs initializations. The flags argument
37 /*	is ignored; pattern_list specifies a list of string patterns.
38 /*
39 /*	string_list_match() matches the specified string against the
40 /*	compiled pattern list.
41 /*
42 /*	string_list_free() releases storage allocated by string_list_init().
43 /* DIAGNOSTICS
44 /*	Fatal error: unable to open or read a pattern file or table.
