+/*++
+/* NAME
+/*	mail_trigger 3
+/* SUMMARY
+/*	trigger a mail service
+/* SYNOPSIS
+/*	#include <mail_proto.h>
+/*
+/*	int	mail_trigger(class, service, request, length)
+/*	const char *class;
+/*	const char *service;
+/*	const char *request;
+/*	ssize_t	length;
+/* DESCRIPTION
+/*	mail_trigger() wakes up the specified mail subsystem, by
+/*	sending it the specified request. In the case of non-FIFO
+/*	server endpoints, a short-running program should invoke
+/*	event_drain() to ensure proper request delivery.
+/*
+/*	Arguments:
+/* .IP class
+/*	Name of a class of local transport channel endpoints,
+/*	either \fIpublic\fR (accessible by any local user) or
+/*	\fIprivate\fR (administrative access only).
+/* .IP service
+/*	The name of a local transport endpoint within the named class.
+/* .IP request
+/*	A string. The list of valid requests is service specific.
+/* .IP length
+/*	The length of the request string.
+/* DIAGNOSTICS
+/*	The result is -1 in case of problems, 0 otherwise.
+/*	Warnings are logged.
+/* BUGS
+/*	Works with FIFO or UNIX-domain services only.
+/*
+/*	Should use master.cf to find out what transport to use.
+/* SEE ALSO
+/*	fifo_trigger(3) trigger a FIFO-based service
+/*	unix_trigger(3) trigger a UNIX_domain service
+/* LICENSE
+/* .ad
+/* .fi
+/*	The Secure Mailer license must be distributed with this software.
