[Gambas-user] external functions and structs

[T Lee Davidson]

Try this:

Public Struct AIS_State
    msgid As Byte                               'Message ID 0 - 31
    sequence As Short                         'era DWORD; / / ! < VDM message sequence number
    total As Short                            'era DWORD; / / ! < Total # Of parts For the message
    num As Short                              'era DWORD; / / ! < Number Of the Last part stored
    channel As Byte                             ': Char; / / ! < AIS Channel character
    six_state As Struct SixBit                         '; / / ! < sixbit parser state
End Struct

Notice: six_state As *Struct* SixBit
