Shuffling function addresses in C/C++ with MSVC

The Microsoft C/C++ compiler allows you to specify link order of functions or variables. Using the #pragma directive with either code_seg or data_seg and specifying the segment name and its sorting key, you can tell the linker how to place the object code in the final executable.

Let’s start with a simple example:

#pragma code_seg(push, ".text$EB009")
__declspec(noinline) void f1()
{
    printf("this is f1()\n");
}
#pragma code_seg(pop)


#pragma code_seg(push, ".text$EB005")
__declspec(noinline) void f2()
{
    printf("this is f2()\n");
}
#pragma code_seg(pop)


#pragma code_seg(push, ".text$EB001")
__declspec(noinline) void f3()
{
    printf("this is f3()\n");
}
#pragma code_seg(pop)

int main()
{
    f1();
    f2();
    f3();
    return 0;
}

When the code_seg pragma is used, we can specify where the subsequent code should lie (in which section in the PE file). When the section name contains the “$” sign, then the subsequent text is not part of the section name (the string prior to the “$”) and instead is used as a sorting key.

Klara with Guitar

During my short visit to Brussels, Belgium this year, I met another street performer: her name is Klara and she had a lovely voice. Unlike other public performers though, she was not friendly so I could not interview her and share with you part of her story. We will have to contend with just a short video I captured:

Meet Roger, the man who lives in the Amsterdam Airport Schiphol


I was traveling from the US to Europe and I had a layover in Amsterdam. In the men’s room, I met an interesting character called Roger. Roger, in his mid forties, was neat and dressed like a backpack traveler. He started a conversation with me, talking about random stuff. At one point, out of the blue he mentions that he lives in the airport. I was not sure what he meant but he explained that he literally lives in the airport. I asked him if he showers, sleeps and gets his basic needs met in the airport and he said yes. In fact, he uses the handicap toilet to wash himself at nights then he goes to sleep in the airport pretending to be an early morning passenger. In the morning, he also uses to toilets to get himself ready and then leaves the airport for the day.

What an interesting encounter. I had no idea that some people, out of necessity do that. I have walked in the streets of popular European cities and I have met many homeless people. Panhandling and sleeping on the street is a second nature to them unfortunately. Roger at least, gets a warm place and washes himself instead of sleeping out in the freezing cold in the winter.

The frugal business man and the sailor

One time, a frugal business man was almost drowning when the cruise ship started sinking. A young sailor throws himself in the water and saves the men. After they arrived to the shore, the frugal business man reached out to his pocket to give the sailor a reward for saving his life. The business man handed him 10$ and said “Thank you”. All the people around the business man, witnessing the situation got disgusted at how cheap the business man and how feeble is the payback for the sailor who saved his life. The sailor then calms the people down and tells them: “He knows more than any of us how much his life is worth”.

A universal grace prayer

Back in 2007, I went to India to do Dyan Yatra (a spiritual trek/pilgrimage to the foothills of the Himalayas to visit ancient temples). We were a group of 120 people traveling in 4 buses containing 30 people each. We would drive to the foothills of a mountain range, then hike up around 8 to 10 km to reach a small village and the temple we wanted to visit. We would sleep in the village and hike back down the next day and resume our pilgrimage.

One day, we got stuck in a village because of a landslide blocking the road. We stayed an extra day in the village and this is when I befriended an Indian who’s both a homeopathic doctor and a Yogi. I had an extensive chat with him and he ended up teaching me a few handy spiritual practices. One of the things that I still remember and practice to this day was the prayer he taught me to say before eating. It is akin to the Christians’ grace prayer that is recited before food is consumed.

If you follow my blog, you may have noticed that I love two things: Prayers and Stories. Anyway, his version of the prayer goes something like this:

Oh my creator and God, thank you for this food. May this food nourish my body, may it be converted into blood and energy that I can use to help and serve others.

This is a very short prayer and is almost devoid of any religious affiliations. It is not a Christian prayer, it is not a Muslim prayer and it surely not a Buddhist or Hindu prayer. It is a simple remembrance that we are grateful for the grace we have in our life and how we intended to return this grace by serving others.
