GLOBAL ROUTINE scan_pkt (packet, pid, uid, cap) =
!++
! FUNCTIONAL DESCRIPTION:
!
! This routine scans an incoming IPCF packet, and validates the
! format and content of that packet. There are two types of packets:
! primary packets initiate the posting of a message to MX; secondary
! packets are used when there is more information needed to complete
! the posting of a message. Primary packets must contain the file
! name of the message to be posted. Primary packets indicate whether
! there will be secondary packets for this message by the cell hdr_state
! which contains $msg_incomplete if there are more packets to come.
! The last packet in a sequence contains the value $msg_complete in this
! cell.
!
! Packets are sequenced, and must arrive in sequence. If a packet is
! found to be out of sequence, the message is invalidated, and an error
! returned to the user agent (usually MS).
!
! FORMAL PARAMETERS:
!
! packet - IPCF packet
! pid - sender's IPCF PID
! uid - sender's user number (TOPS20) or PPN (TOPS10)

! FUNCTIONAL DESCRIPTION:
!
! This routine returns an asciz string representing the userid. On
! TOPS-20 this is the output of a DIRST. On TOPS-10, this is either the
! username from the accounting system, or his PPN converted to a string if no
! accounting entry exists for the PPN. If the resulting string contains
! special characters, quotes are put around the offending string. An @
! followed by the local node name is appended to the string.
! In addition, MX's internal servers generate UID's that look like
! <-1,,ADDR> where ADDR is the address of an ASCIZ string. In this case, a
! copy of the asciz string beginning at ADDR will be returned. This is used
! by MX's internal servers (such as MAIL-11 and SMTP) to set up appropriate
! log file entries.
!
! FORMAL PARAMETERS:
!
! UID:
! TOPS-20: a user number/directory number suitable for DIRST or
! <-1,,ADDR>
! TOPS-10: a PPN or <-1,,ADDR>
!
! VFLG: An address in which to return 1 if this is a valid user, and
! 0 otherwise.
