FileHandle :: struct { fd: s32; valid: bool; }

DirectoryCursor :: struct { storage: *void; valid: bool; failed: bool; }

DirectoryKind :: enum { Unknown = 0; Directory = 4; Regular = 8; Link = 10; Other = 255; }

DirectoryEntry :: struct { name: [256]u8; name_count: s32; valid: bool; kind: DirectoryKind; }

OpenRead :: (path: string) -> FileHandle

OpenUpdate :: (path: string) -> FileHandle

OpenWrite :: (path: string) -> FileHandle

OpenReplace :: (path: string) -> FileHandle

OpenNew :: (path: string) -> FileHandle

Create a writable file only when the path is unoccupied, including by a symbolic link. Creation is exclusive in the same native open operation.

OpenExclusivePrivate :: (path: string) -> FileHandle

RemoveFile :: (path: string) -> bool

PathIsLink :: (path: string) -> bool

Inspect the path itself, including a dangling link. No target is opened, no result is cached, and invalid paths cannot be shortened at a NUL. Windows includes junctions and other reparse points in this link policy.

PathExists :: (path: string) -> bool

DirectoryExists :: (path: string) -> bool

RenamePath :: (source: string, destination: string) -> bool

RenameNoReplace :: (source: string, destination: string) -> bool

LinkFile :: (source: string, destination: string) -> bool

CreateDirectory :: (path: string) -> bool

CreatePrivateDirectory :: (path: string) -> bool

FileSize :: (file: FileHandle) -> s64

ReadAt :: (file: FileHandle, output: []u8, offset: s64) -> s64

WriteAt :: (file: FileHandle, input: []u8, offset: s64) -> s64

WriteTextAt :: (file: FileHandle, input: string, offset: s64) -> s64

Copy immutable text through a bounded buffer before writing it. The string may borrow read-only storage, so it must not be exposed as a mutable slice.

CloseFile :: (file: FileHandle) -> bool

SyncFile :: (file: FileHandle) -> bool

Read :: (file: FileHandle, output: []u8) -> s64

Write :: (file: FileHandle, input: []u8) -> s64

OpenDirectory :: (path: string) -> DirectoryCursor

NextDirectoryEntry :: (cursor: *DirectoryCursor) -> DirectoryEntry

CloseDirectory :: (cursor: *DirectoryCursor) -> bool
