/* NAME
/* addr_match_list 3
/* SUMMARY
/* address list membership
/* SYNOPSIS
/* #include <addr_match_list.h>
/*
/* ADDR_MATCH_LIST *addr_match_list_init(pname, flags, pattern_list)
/* const char *pname;
/* int flags;
/* const char *pattern_list;
/*
/* int addr_match_list_match(list, addr)
/* ADDR_MATCH_LIST *list;
/* const char *addr;
/*
/* void addr_match_list_free(list)
/* ADDR_MATCH_LIST *list;
/* DESCRIPTION
/* This is a convenience wrapper around the match_list module.
/*
/* This module implements tests for list membership of a
/* network address.
/*
/* A list pattern specifies an internet address, or a network/mask
/* pattern, where the mask specifies the number of bits in the
/* network part. When a pattern specifies a file name, its
/* contents are substituted for the file name; when a pattern
/* is a type:name table specification, table lookup is used
/* instead. Patterns are separated by whitespace and/or commas.
/* In order to reverse the result, precede a pattern with an
/* exclamation point (!).
/*
/* A host matches a list when its address matches a pattern.
/* The matching process is case insensitive.
/*
/* addr_match_list_init() performs initializations. The pname
/* argument specifies error reporting context. The flags
/* argument is the bit-wise OR of zero or more of the following:
/* .IP MATCH_FLAG_RETURN
/* Request that addr_match_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 is a list of patterns, or the absolute
/* pathname of a file with patterns.
/*
/* addr_match_list_match() matches the specified host address
/* against the specified list of patterns.
/*
/* addr_match_list_free() releases storage allocated by
/* addr_match_list_init().
/* DIAGNOSTICS
/* Fatal errors: unable to open or read a pattern file; invalid
/* pattern. Panic: interface violations.
/* SEE ALSO
/* match_list(3) generic list matching
/* match_ops(3) match host by name or by address
