Synchronization parameters
Indicates that there should be no downloads in the current synchronization, which can save communication time, especially over slow communication links. When set to true, the client waits for the upload acknowledgement from the MobiLink synchronization server, after which it terminates the synchronization session successfully.
The parameter is an optional Boolean value, and by default is false.
Set the parameter to true as follows:
ul_synch_info info; // ... info.upload_only = ul_true;
