I'm looking for Profibus cards (and other bus architectures like CAN bus
Modbus, ...) and driver working on Linux.
Please tell me where can I find more about Hilscher.

memset is defined as macro I think, you have to include a Linux header,

fprintf is a bigger problem. You should write your own fprintf function
which outputs via rtl_printf ore printk.
