The standard library Winix_Base_Io_Driver_For_Os__Premicrothread api defines the low-level api exported by the Mythryl platform-specific file I/O driver for a particular operating system.
The Winix_Base_Io_Driver_For_Os__Premicrothread api is implemented by the winix_base_file_io_driver_for_posix_g generic from src/lib/std/src/io/winix-base-file-io-driver-for-posix-g–premicrothread.pkg[
The Winix_Base_Io_Driver_For_Os__Premicrothread api source code is in src/lib/std/src/io/winix-base-file-io-driver-for-os–premicrothread.api.
