+/*++
+/* NAME
+/*	argv_attr_print
+/* SUMMARY
+/*	write ARGV to stream
+/* SYNOPSIS
+/*	#include <argv_attr.h>
+/*
+/*	int	argv_attr_print(print_fn, stream, flags, ptr)
+/*	ATTR_PRINT_COMMON_FN print_fn;
+/*	VSTREAM *stream;
+/*	int	flags;
+/*	void	*ptr;
+/* DESCRIPTION
+/*	argv_attr_print() writes an ARGV to the named stream using
+/*	the specified attribute print routine. argv_attr_print() is meant
+/*	to be passed as a call-back to attr_print(), thusly:
+/*
+/*	... SEND_ATTR_FUNC(argv_attr_print, (const void *) argv), ...
+/* DIAGNOSTICS
+/*	Fatal: out of memory.
+/*
+/*	The result value is zero in case of success, non-zero
+/*	otherwise.
+/* LICENSE
