+/*++
+/* NAME
+/*	match_parent_style 3
+/* SUMMARY
+/*	parent domain matching control
+/* SYNOPSIS
+/*	#include <match_parent_style.h>
+/*
+/*	int	match_parent_style(name)
+/*	const char *name;
+/* DESCRIPTION
+/*	This module queries configuration parameters for the policy that
+/*	controls how wild-card parent domain names are used by various
+/*	postfix lookup mechanisms.
+/*
+/*	match_parent_style() looks up "name" in the
+/*	parent_domain_matches_subdomain configuration parameter
+/*	and returns either MATCH_FLAG_PARENT (parent domain matches
+/*	subdomains) or MATCH_FLAG_NONE.
+/* DIAGNOSTICS
+/*	Fatal error: out of memory, name listed under both parent wild card
+/*	matching policies.
+/* SEE ALSO
+/*	string_list(3) plain string matching
+/*	domain_list(3) match host name patterns
+/*	namadr_list(3) match host name/address patterns
