Receive a 32-bit Integer from a Socket

See more Socket/SSL/TLS Examples

Demonstrates Socket.ReceiveInt32, which reads exactly four bytes as a signed 32-bit integer and stores the result in the ReceivedInt property. Byte order is selectable.

#import <CkoSocket.h>

BOOL success = NO;

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

//  Connect to the server using TLS.
BOOL bTls = YES;
int maxWaitMs = 5000;
success = [socket Connect: @"example.com" port: [NSNumber numberWithInt: 5000] ssl: bTls maxWaitMs: [NSNumber numberWithInt: maxWaitMs]];
if (success == NO) {
    NSLog(@"%@",socket.LastErrorText);
    return;
}

//  Read exactly four bytes as a signed 32-bit integer and store the result in the ReceivedInt
//  property.  The argument selects byte order (true = big-endian, network byte order).
BOOL bBigEndian = YES;
success = [socket ReceiveInt32: bBigEndian];
if (success == NO) {
    NSLog(@"%@",socket.LastErrorText);
    return;
}

NSLog(@"%@%d",@"Received 32-bit integer: ",[socket.ReceivedInt intValue]);
