§Raw FFI bindings for the uldaq library

This crate provides raw FFI bindings to the uldaq library, used for interacting with Measurement Computing / Data Translation DAQ devices on Linux.

These bindings are unsafe and low-level. For a safe, ergonomic wrapper around this crate, have a look at the [uldaqrs] crate.

For documentation of all exported structs and functions, please have a look at the upstream code.
