+The `remote:` represents the configured [url](#http-url), and any path following

+changes - as described next.
+
+### Windows C/C++ guidelines
+
+The official [C example](#linux-c-example) is targeting Linux/macOS, and will
+not work on Windows. It is very possible to use `librclone` from a C/C++
+application on Windows, but there are some pitfalls that you can avoid by
+following these guidelines:
+- Build `librclone` as shared library, and use run-time dynamic linking (see [linking](#linking)).
+- Do not try to unload the library with `FreeLibrary` (see [unloading](#unloading)).
+- Deallocate returned strings with API function `RcloneFreeString` (see [memory management](#memory-management)).
+- Define struct `RcloneRPCResult`, instead of including `librclone.h` (see [include file](#include-file)).
+- Use UTF-8 encoded strings (see [encoding](#encoding)).
+- Properly escape JSON strings, beware of the native path separator (see [escaping](#escaping)).
+
+#### Linking
+
+Use of different compilers, compiler versions, build configuration, and
+dependency on different C runtime libraries for a library and the application
+that references it, may easily break compatibility. When building the librclone
+library with MinGW GCC compiler (via go build command), if you link it into an
+application built with Visual C++ for example, there will be more than enough
+differences to cause problems.
+
+Linking with static library requires most compatibility, and is less likely to
+work. Linking with shared library is therefore recommended. The library exposes
+a plain C interface, and by using run-time dynamic linking (by using Windows API
+functions `LoadLibrary` and `GetProcAddress`), you can make a boundary that
+ensures compatibility (and in any case, you will not have an import library).
+The only remaining concern is then memory allocations; you should make sure
+memory is deallocated in the same library where it was allocated, as explained
+[below](#memory-management).
+
+#### Unloading
+
+Do not try to unload the library with `FreeLibrary`, when using run-time dynamic
+linking. The library includes Go-specific runtime components, with garbage
+collection and other background threads, which do not handle unloading. Trying
+to call `FreeLibrary` will crash the application. I.e. after you have loaded
+`librclone.dll` into your application it must stay loaded until your application
+exits.
+
+#### Memory management
+
+The output string returned from `RcloneRPC` is allocated within the `librclone`
+library, and caller is responsible for freeing the memory. Due to C runtime
+library differences, as mentioned [above](#linking), it is not recommended to do
+this by calling `free` from the consuming application. You should instead use
+the API function `RcloneFreeString`, which will call `free` from within the
+`librclone` library, using the same runtime that allocated it in the first
+place.
+
+#### Include file
+
+Do not include `librclone.h`. It contains some plain C, golang/cgo and GCC
+specific type definitions that will not compile with all other compilers
+without adjustments, where Visual C++ is one notable example. When using
+run-time dynamic linking, you have no use of the extern declared functions
+either.
+
+The interface of librclone is so simple, that all you need is to define the
+small struct `RcloneRPCResult`, from [librclone.go](librclone.go):
+
+```C++
+struct RcloneRPCResult {
+    char* Output;
+    int	Status;
+};
+```
+
+#### Encoding
+
+The API uses plain C strings (type `char*`, called "narrow" strings), and rclone
+assumes content is UTF-8 encoded. On Linux systems this normally matches the
+standard string representation, and no special considerations must be made. On
+Windows it is more complex.
+
+On Windows, narrow strings are traditionally used with native non-Unicode
+encoding, the so-called ANSI code page, while Unicode strings are instead
+represented with the alternative `wchar_t*` type, called "wide" strings, and
+encoded as UTF-16. This means, to correctly handle characters that are encoded
+differently in UTF-8, you will need to perform conversion at some level:
+Conversion between UTF-8 encoded narrow strings used by rclone, and either ANSI
+encoded narrow strings or wide UTF-16 encoded strings used in runtime function,
+Windows API, third party APIs, etc.
+
+#### Escaping
+
+The RPC method takes a string containing JSON. In addition to the normal
+escaping of strings constants in your C/C++ source code, the JSON needs its
+own escaping. This is not a Windows-specific issue, but there is the
+additional challenge that native filesystem path separator is the same as
+the escape character, and you may end up with strings like this:
+
+```C++
+const char* input = "{"
+"\"fs\": \"C:\\\\Temp\","
+"\"remote\": \"sub/folder\","
+"\"opt\": \"{\\\"showHash\\\": true}\""
+"}";
+```
+
+With C++11 you can use raw string literals to avoid the C++ escaping of string
+constants, leaving escaping only necessary for the contained JSON.
