   6 /* SUMMARY
   7 /*      write MSG_STATS structure to stream
   8 /* SYNOPSIS
   9 /*      #include <msg_stats.h>
  10 /*
  11 /*      int     msg_stats_print(print_fn, stream, flags, ptr)
  12 /*      ATTR_PRINT_MASTER_FN print_fn;

  16 /* DESCRIPTION
  17 /*      msg_stats_print() writes an MSG_STATS structure to the named
  18 /*      stream using the specified attribute print routine.
  19 /*      msg_stats_print() is meant to be passed as a call-back to
  20 /*      attr_print(), thusly:
  21 /*
  22 /*      ... ATTR_TYPE_FUNC, msg_stats_print, (void *) stats, ...
  23 /* DIAGNOSTICS
  24 /*      Fatal: out of memory.
