Receive an Exact Number of Bytes as Encoded Text

See more Socket/SSL/TLS Examples

Demonstrates Socket.ReceiveNBytesENC, which receives exactly the requested number of bytes and returns them encoded using a named encoding. It waits until the full count is received.

load ./chilkat.dll

set success 0

set socket [new_CkSocket]

#  Connect to the server using TLS.
set bTls 1
set maxWaitMs 5000
set success [CkSocket_Connect $socket "example.com" 5000 $bTls $maxWaitMs]
if {$success == 0} then {
    puts [CkSocket_lastErrorText $socket]
    delete_CkSocket $socket
    exit
}

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

#  Receive exactly the requested number of bytes and return them encoded using the named encoding.
#  Unlike ReceiveBytesENC, this waits until the full count has been received.
