n_to_b

ULONG n_to_b(

unsigned char* b , N a ) ;

len = n_to_b(unsigned char *buf, N a) -- convert a to bytes, most
significant byte first. Returns number of bytes written to buf. buf
should be large enough to hold sizeof(NN) bytes. (Note that number
is handled as unsigned, negative value converts to sizeof(NN) bytes.)
(XXX check portablility when converting to not-16/32 bit machine)
