Hi Adam,

Thanks for your reply as always.

My library calls l4_ipc_wait() a few times and fprov-l4/dump-l4 only
makes IPC calls. I can port my library to to use the standard Linux
semaphore and thread libraries but I still need to receive IPC calls.

Any suggestions for L4Linux app example code that waits for an IPC?

Thanks
Leon
