| #define DTN_OPTION_TXCHUNKSIZE 1 |
Allow to set the bundlesize when using "dtn_write" API. Every DTN_OPTION_CHUNKSIZE bytes a new bundle is created Resetting TX_CHUNKSIZE forces flushing of current tx_buffer

Blocking read. This can only be used if the process_bundle callback was NULL in register_endpoint. Returns number of bytes read, or <0 if shit happened

Register an endpoint on local device.Tries to grab dtn://<this_nodes_address>/<ep> Returns DTN endpoint descriptor on success, or a vlaue <0 if shit happens If receive and notification callbacks are given, they'll be called in case of received data (all data has to fit in RAM in this case) or notifications. Access to process_bundle und dtn_notification is serialized, no need t make them reentrant
