cajeta.io.file.FileWriter — streaming byte writer, returned by File.openWrite(path, mode). The caller hands in (data, len) per call; the native write loops past OS-level short writes so every byte lands, but there is no user-space buffer — bytes go straight to the syscall. Write String payloads with writeString, raw bytes with write. Call close() when done.

FileWriter w #= File.openWrite("/tmp/out.txt", OpenMode.APPEND);
w.writeString("first line\n");
int8[] bytes = heap int8[2];
w.write(bytes, 2);
w.flush();
w.close();

Methods

Signature
`void write(int8[] data, int32 len)` ⚑	Write `data[0..len)` to the file; tolerates partial OS writes internally
`void writeString(String s)` ⚑	Write a `String`’s UTF-8 bytes to the file
`void flush()`	Currently a no-op (writes are unbuffered); does not `fsync` — durability is `File.sync()`
`void close()`	Flush + close the underlying fd; idempotent

⚑ = @EntryPoint
