 * Check address space (B string)

 *	either '\0' or the max byte is valid.
 *	If max = 0, the number of bytes (max) is ignored.
 *	If the memory area is valid, the value returned is either
 *	the number of bytes or the max value (through to the max
 *	byte with max !=0 and no '\0').
 *	If the memory area is not valid, the error code is returned.
