// this file is an example of how to intercept a C++ method by using the
// LD_PRELOAD environment variable of the GNU dynamic linker.
//
// it works like this:
//
// 1) define a method that will have the same symbol as the intercepted
//    method when compiled. For example, the method Foo::getValue()
//    defined here has the mangled symbol "_ZNK3Foo8getValueEv".
//    tools like nm, objdump or readelf can display the symbols of
//    binaries. note that depending on compiler and linker options,

// I wrote this bookmarklet because Amazon has ended Linux support for downloading MP3s,
// and now I have to download songs separately through Amazon Cloud Player.
// This bookmarklet helps a bit with this, but it's far from perfect.
// When a list of songs is shown in Amazon Cloud Player, it clicks the song checkbox and
// the download button separately for each song, while waiting a few seconds in between songs.
// I encountered the issue that I cannot download more than a few songs simultaneously;
// the rest will just not show a download window. Not sure whether my browser or the server
// is doing this, but you might want to set the value of songdelayms high enough.

// The script is not really that useful, but it was fun to play around with this.

// In C/C++, the idiom (sizeof(arr) / sizeof(*arr)) is often used to get the length of an array.
// But this will return incorrect results if arr is not actually an array, but a pointer.
// The following function template provides a type-safe way to get the length of an array,
// by "destructuring" the type and reading the array length from there.
