Send Bytes on a Socket Connection

See more Socket/SSL/TLS Examples

Demonstrates how to send a mixture of binary (non-text) and text bytes on a socket connection. Objective-C

#import <CkoSocket.h>
#import <CkoBinData.h>

BOOL success = NO;

// This example requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

CkoSocket *socket = [[CkoSocket alloc] init];

// Connect to some host:port
BOOL ssl = NO;
int maxWaitMillisec = 20000;
int port = 5555;
success = [socket Connect: @"test.com" port: [NSNumber numberWithInt: port] ssl: ssl maxWaitMs: [NSNumber numberWithInt: maxWaitMillisec]];
if (success != YES) {
    NSLog(@"%@",socket.LastErrorText);
    return;
}

// We wish to send a 0x00 byte followed by the us-ascii string "10800"
CkoBinData *bd = [[CkoBinData alloc] init];

[bd AppendByte: [NSNumber numberWithInt: 0]];
[bd AppendString: @"10800" charset: @"utf-8"];

// Send the entire contents of bd.
success = [socket SendBd: bd offset: 0 numBytes: 0];
if (success != YES) {
    NSLog(@"%@",socket.LastErrorText);
    return;
}
