//! Definitions of upstream [libc] items used within the crate.

// We cannot use the libc crate directly.
// This is because the sallyport crate is a dependency of the enarx shims,
// which support the x86_64-unknown-none target,
// and the libc crate doesn't contain the proper symbols when compiled for that target
// (which is correct, as the "none" in our target triple's OS field indicates).
// Ideally we would not need to maintain these definitions ourselves;
// instead, the ideal solution would be for the official libc crate to be split
// into platform-specific crates, with the libc crate being a facade,
// and we could then depend on the Linux-specific crate directly.
