+/*++
+/* 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
