Function clockbound_open 

#[unsafe(no_mangle)]
pub unsafe extern "C" fn clockbound_open(
    clockbound_shm_path: *const c_char,
    err: *mut clockbound_err,
) -> *mut clockbound_ctx

Open and create a reader to the Clockbound shared memory segment.

Create a ShmReader pointing at the path passed to this call, and package it (and any other side information) into a clockbound_ctx. A reference to the context is passed back to the C caller, and needs to live beyond the scope of this function.

Safety

Rely on the caller to pass valid pointers.
