+/*++
+/* 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_MASTER_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, (void *) argv), ...
+/* DIAGNOSTICS
+/* Fatal: out of memory.
+/*
+/* The result value is zero in case of success, non-zero
+/* otherwise.
