Receive an Exact Number of Bytes into a BinData

See more Socket/SSL/TLS Examples

Demonstrates Socket.ReceiveBdN, which receives exactly the requested number of bytes and appends them to a BinData, continuing until the full count is satisfied.

require 'chilkat'

success = false

socket = Chilkat::CkSocket.new()

#  Connect to the server using TLS.
bTls = true
maxWaitMs = 5000
success = socket.Connect("example.com",5000,bTls,maxWaitMs)
if (success == false)
    print socket.lastErrorText() + "\n";
    exit
end

#  MaxReadIdleMs controls the inactivity limit for receiving.  The ReceiveBdN call will fail if
#  incoming bytes halt for longer than this many milliseconds before the full amount is received.
socket.put_MaxReadIdleMs(15000)

#  Receive exactly the requested number of bytes, appending them to a BinData.  The method continues
#  receiving until the full count is satisfied or a failure occurs.
bd = Chilkat::CkBinData.new()
success = socket.ReceiveBdN(256,bd)
if (success == false)
    print socket.lastErrorText() + "\n";
    exit
end

print "Received " + bd.get_NumBytes().to_s() + " bytes." + "\n";
