/*
 * This file is not directly part of the frontlib and is not required to build it.
 * However, it is recommended to include it in compilation when building for Android. The purpose of this file
 * is to ensure consistency between the function signatures of the JNA Java bindings of the Android port and the
 * frontlib functions.
 *
 * This file, in essence, consists only of function declarations. They are duplicates of function declarations
 * from the frontlib headers that are referenced from JNA bindings. If the signature of one of these functions
 * changes in the frontlib, it will no longer match the signature in this file, and the compiler will show an error.
 * If that happens, you need to update the JNA bindings in Hedgeroid to match the new function signature, and then
 * update this file.
 *
 * The reason for all this is that JNA does not actually know the function signatures of the functions it binds,
 * it derives them from Java method declarations. If those do not match the actual function signatures, you will
 * only notice when you suddenly get strange (and possibly hard to track down) problems at runtime. This file is
 * an attempt to detect these problems at compile time instead. Notice that it will NOT detect changes to structs
 * or constants though, which also require updates to the JNA bindings.
 */

/*
 * Before we include the frontlib headers, we define away the const keyword. This is necessary because there is no
 * distinction between const and non-const types on the JNA side, and we don't want the compiler to complain because
 * of bad constness.
 *
 * This is so evil, but it works...
