NAME

	WriteBattMem -- Write a bitstring to nonvolatile ram.  (V36)

SYNOPSIS

	Error = WriteBattMem( Buffer, Offset, Len )
	D0                    A0      D0      D1
	ULONG WriteBattMem( APTR, ULONG, ULONG );

FUNCTION

	Write a bitstring to the nonvolatile ram.

INPUTS

	Buffer          Where to get the bitstring.
	Offset          Bit offset of first bit to write.
	Len             Length of bitstring to write.

RESULT

	Error           Zero if no error.

NOTES

	The battery-backed memory is checksummed. If a checksum error
	is detected, all bits in the battery-backed memory are
	silently set to zero.
	Partial byte writes (less than 8 bits) result in the bits
	written being read from the low-order bits of the source byte.
