/* 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.
