To allow non-POSIX platforms such as Windows to support WASI libc filesystem functionality, create a set of wrapper functions which provide a platform-agnostic interface to interact with the host filesystem. For now, the Windows implementation is stubbed but this will be implemented properly in a future PR. There are no functional changes in this change, just a reorganization of code to move any direct POSIX references out of posix.c in the libc implementation into posix_file.c under the shared POSIX sources. See https://github.com/bytecodealliance/wasm-micro-runtime/issues/2495 for a more detailed overview of the plan to port the WASI libc filesystem to Windows.
This folder contains the platform abstract layer for multiple platforms. To support a new platform, you can simply create a new folder here and implement all the APIs defined in include folder.
