Message Information Level 1

struct msg_info_1 {
   unsigned char  msgi1_name[CNLEN+1];
   unsigned char  msgi1_forward_flag;
   unsigned char  msgi1_pad1;
   unsigned char  msgi1_forward[CNLEN+1];
};

where:

• The first field in this data structure is identical to that in the previous level.

• msgi1_forward_flag specifies whether messages are sent to a name on the local computer or forwarded to a name on a remote computer. The following are the possible values: ┌───────┬───────────────────────────┬──────────────────────────────────────────┐
  │ BIT │ SYMBOLIC CONSTANT │ MEANING │
  ├───────┼───────────────────────────┼──────────────────────────────────────────┤
  │ 0-1 │ MSGNAME_NOT_FORWARDED │ Reserved; must be 0. │
  ├───────┼───────────────────────────┼──────────────────────────────────────────┤
  │ 2 │ MSGNAME_FORWARDED_TO │ If 1, specifies a name on a remote com- │
  │ │ │ puter. │
  ├───────┼───────────────────────────┼──────────────────────────────────────────┤
  │ 3 │ MSGNAME_NOT_FORWARDED │ Reserved; must be 0. │
  ├───────┼───────────────────────────┼──────────────────────────────────────────┤
  │ 4 │ MSGNAME_FORWARDED_FROM │ If 1, specifies a name on the local com- │
  │ │ │ puter. │
  ├───────┼───────────────────────────┼──────────────────────────────────────────┤
  │ 5-7 │ MSGNAME_NOT_FORWARDED │ Reserved; must be 0. │
  └───────┴───────────────────────────┴──────────────────────────────────────────┘
  

• msgi1_pad1 word-aligns the data structure components.

• msgi1_forward is an ASCIIZ string specifying the name to which the message will be sent if messages are to be forwarded.
