Receive a Block of Bytes to a File

See more Socket/SSL/TLS Examples

Demonstrates Socket.ReceiveBytesToFile, which receives one available block of bytes and appends it to a file.

The file path is relative to the application's current working directory. An absolute path may also be used. Supply the path appropriate to your own environment.

#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;
}

//  The file path is relative to the application's current working directory.  An absolute path
//  may also be used.  Supply the path appropriate to your own environment.

//  Receive one available block of bytes and append it to a file.  If bytes are already buffered,
//  they are used first; otherwise a single receive operation is performed.
success = [socket ReceiveBytesToFile: @"qa_output/received.dat"];
if (success == NO) {
    NSLog(@"%@",socket.LastErrorText);
    return;
}

NSLog(@"%@",@"Received block appended to the file.");
