Description
Presently rustls-ffi takes a dependency on the libc crate for the following imports:
size_tc_voidc_charc_uintc_intEINVALEIO
It looks like the core::ffi module has many of these same defines, and could potentially let us drop an external dependency.
Blockers:
-
core::ffi::c_size_tis unstable (upstream tracking issue). -
EINVALandEIOaren't present; I think we would need our own platform-gated constants for these.
I propose we wait for c_size_t to stablize and then replace libc with core::ffi::* and manually defined EINVAL/EIO.
Contributor guide

- Comment on the issue to say you are picking it up — it saves two people doing the same work.
- Fork the repository and make your change on a branch.
- Open a pull request that references the issue number.
Research direction
The issue names no files or tests; start by reviewing rustls-ffi's current libc imports and the stabilization status of core::ffi::c_size_t. Check how platform-gated EINVAL and EIO constants would be defined, and confirm libc can be removed without changing the FFI types or error behavior.
