Synchronize local and remote directory trees by uploading newer or missing files to the remote server. Objective-C

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

CkoSsh *ssh = [[CkoSsh alloc] init];

//  Hostname may be an IP address or hostname:
NSString *hostname = @"www.some-ssh-server.com";
int port = 22;

//  Connect to an SSH server:
success = [ssh Connect: hostname port: [NSNumber numberWithInt: port]];

//  Wait a max of 5 seconds when reading responses..

//  Authenticate using login/password:

//  Once the SSH object is connected and authenticated, we use it

//  Upload synchronization modes:
//  mode=0: Upload all files
//  mode=1: Upload all files that do not exist on the FTP server.
//  mode=2: Upload newer or non-existant files.
//  mode=3: Upload only newer files.  If a file does not already exist on the FTP server, it is not uploaded.
//  mode=4: transfer missing files or files with size differences.
//  mode=5: same as mode 4, but also newer files.

//  Additional files and directores can be excluded by setting the SyncMustNotMatch property.
//  The SyncMustNotMatch patterns apply only to the final filename or directory part of a path.
//  If a directory matches, then it will not be traversed in a recursive traversal.
//

//  The SyncMustMatch property can be set to restrict the files uploaded to only those
//  matching at least one pattern in a set.

//  Do the recursive sync to upload newer or non-existant files:
BOOL bRecurse = YES;

//  The files actually uploaded can be examined in the SyncedFiles property.
//  It is a string property that contains the relative path, one per line, of each
//  file uploaded.
