/* NAME
/* string_list 3
/* SUMMARY
/* match a string against a pattern list
/* SYNOPSIS
/* #include <string_list.h>
/*
/* STRING_LIST *string_list_init(pname, flags, pattern_list)
/* const char *pname;
/* int flags;
/* const char *pattern_list;
/*
/* int string_list_match(list, name)
/* STRING_LIST *list;
/* const char *name;
/*
/* void string_list_free(list)
/* STRING_LIST *list;
/* DESCRIPTION
/* This is a convenience wrapper around the match_list module.
/*
/* This module implements tests for list membership of a string.
/*
/* Patterns are separated by whitespace and/or commas. A pattern
/* is either a string, a file name (in which case the contents
/* of the file are substituted for the file name) or a type:name
/* lookup table specification.
/*
/* A string matches a string list when it appears in the list of
/* string patterns. The matching process is case insensitive.
/* In order to reverse the result, precede a pattern with an
/* exclamation point (!).
/*
/* string_list_init() performs initializations. The pname
/* argument specifies error reporting context. The flags argument
/* is a bit-wise OR of zero or more of following:
/* .IP MATCH_FLAG_RETURN
/* Request that string_list_match() logs a warning and returns
/* zero with list->error set to a non-zero dictionary error
/* code, instead of raising a fatal error.
/* .PP
/* Specify MATCH_FLAG_NONE to request none of the above.
/* The last argument specifies a list of string patterns.
/*
/* string_list_match() matches the specified string against the
/* compiled pattern list.
/*
/* string_list_free() releases storage allocated by string_list_init().
/* DIAGNOSTICS
/* Fatal error: unable to open or read a pattern file or table.
/* SEE ALSO
/* match_list(3) generic list matching
/* match_ops(3) match strings by name or by address
