This examples shows usage about SyncML C Toolkit API.
It's based on sample scenarios in SyncML Reference Toolkit Manual.

Sender sends a message adding a vCard to receiver.
And receiver shows the received message from sender.

How to run sender and receiver

1. After building examples, you can get sender and receiver binaries.

2. Run the receiver 
 > receiver (on DOS prompt)
 $ ./receiver (on Unix shell)

3. Run the sender on another DOS prompt or Unix shell
 > sender (on DOS prompt)
 $ ./sender (on Unix shell)
