Hi again,
there where some obvious errors left:
def ae_6 session
pdu, pduLen = session.read(5).unpack(‘cN’)
buffer = session.read(pduLen)
calledAETitle, callingAETitle, itemType, itemLength =
buffer.unpack(‘x4A16A16x35Cxn’)
contextName=buffer[72, itemLength]
start = 72 + itemLength
while start < pduLen
start += getNextPresentationContext(buffer[start…-1])
puts “Finish = #{start - 1} outside proc”
end
end
def getNextPresentationContext(pdu)
it, il, presContextId, itemType, itemLength =
pdu.unpack(‘CxnCx3Cxn’)
abstractSyntax=pdu[12, itemLength]
start = 12 + itemLength
loop do
return start if pdu[start] != 64
itemLength, =pdu[start + 2, 2].unpack('n')
transferSyntax=pdu[start + 4, itemLength]
puts "id=#{presContextId}, AbstractSyntax =#{abstractSyntax},
TxSyntax=#{transferSyntax}"
start += 4 + itemLength
end
end
cheers
Simon
