[libc-commits] [PATCH] D125939: [libc] add fprintf and file_writer

[Siva Chandra via Phabricator via libc-commits]

sivachandra added inline comments.


================
Comment at: libc/src/stdio/printf_core/file_writer.h:23
+  __llvm_libc::File *file = reinterpret_cast<__llvm_libc::File *>(raw_pointer);
+  file->write(to_write, len);
+}
----------------
Is it OK to ignore the return value? For example, if `file` were read only, then `write` would fail. Shouldn't that be reflected in the `fprintf` return value?
