/* NAME

/*
/*	CONFIG_INT_TABLE cleanup_int_table[];
/*
/*	CONFIG_BOOL_TABLE cleanup_bool_table[];
/*
/*	CONFIG_STR_TABLE cleanup_str_table[];

/* DESCRIPTION
/*	This module implements a callable interface to the cleanup service
/*	for one-time initializations that must be done before any message
/*	processing can take place.
/*
/*	cleanup_{int,str,time}_table[] specify configuration
/*	parameters that must be initialized before calling any functions
/*	in this module. These tables satisfy the interface as specified in
/*	single_service(3).
/*
/*	cleanup_pre_jail() and cleanup_post_jail() perform mandatory
/*	initializations before and after the process enters the optional
/*	chroot jail. These functions satisfy the interface as specified
/*	in single_service(3).
/*
/*	cleanup_path is either a null pointer or it is the name of a queue
/*	file that currently is being written. This information is used
/*	by cleanup_all() to remove incomplete files after a fatal error,
/*	or by cleanup_sig() after arrival of a SIGTERM signal.
/*
/*	cleanup_trace_path is either a null pointer or the pathname of a
/*	trace logfile with DSN SUCCESS notifications. This information is
/*	used to remove a trace file when the mail transaction is canceled.
/*
/*	cleanup_all() must be called in case of fatal error, in order
/*	to remove an incomplete queue file.
/*
/*	cleanup_sig() must be called in case of SIGTERM, in order
/*	to remove an incomplete queue file.
/* DIAGNOSTICS
/*	Problems and transactions are logged to \fBsyslogd\fR(8)
/*	or \fBpostlogd\fR(8).
/* SEE ALSO
/*	cleanup_api(3) cleanup callable interface, message processing
