+# z_vcpkg_function_arguments
+
+**Only for internal use in vcpkg helpers. Behavior and arguments will change without notice.**
+Get a list of the arguments which were passed in.
+Unlike `ARGV`, which is simply the arguments joined with `;`,
+so that `(A B)` is not distinguishable from `("A;B")`,
+this macro gives `"A;B"` for the first argument list,
+and `"A\;B"` for the second.
+
+```cmake
+z_vcpkg_function_arguments(<out-var> [<N>])
+```
+
+`z_vcpkg_function_arguments` gets the arguments between `ARGV<N>` and the last argument.
+`<N>` defaults to `0`, so that all arguments are taken.
+
+## Example:
+```cmake
+function(foo_replacement)
+    z_vcpkg_function_arguments(ARGS)
+    foo(${ARGS})
+    ...
+endfunction()
+```
