Push service ObexFTP C client example

Compile with: gcc -Wall -lobexftp -o c_example_obex_push c_example_obex_push.c

Interesting lines are marked with /*!!!*/. The basic sequence is:

• #include <obexftp/client.h>
• obexftp_client_t *cli = NULL;
• channel = obexftp_browse_bt_push(device);
• cli = obexftp_open(OBEX_TRANS_BLUETOOTH, NULL, NULL, NULL);
• ret = obexftp_connect_push(cli, device, channel);
• ret = obexftp_put_file(cli, filename, basename);
• ret = obexftp_disconnect(cli);
• obexftp_close(cli);
