Send a 4-byte Length Prefix over a Socket

See more Socket/SSL/TLS Examples

Demonstrates Socket.SendCount, which sends a four-byte length prefix in network byte order. This is typically used to tell the peer how many bytes follow.

import sys
import chilkat2

success = False

socket = chilkat2.Socket()

# Connect to the server using TLS.
bTls = True
maxWaitMs = 5000
success = socket.Connect("example.com",5000,bTls,maxWaitMs)
if (success == False):
    print(socket.LastErrorText)
    sys.exit()

# Send a four-byte length prefix in network byte order.  A common framing pattern is to send the
# number of bytes in a message before the message itself, so the peer knows exactly how many bytes
# to read.
messageLength = 512
success = socket.SendCount(messageLength)
if (success == False):
    print(socket.LastErrorText)
    sys.exit()

print("Length prefix sent.")
