Creating a Hello World library function in assembly and calling it from C#
- by Filip Ekberg
Let's say we use NASM as they do in this answer: how to write hellow world in assembly under windows.
I got a couple of thoughts and questions regarding assembly combined with c# or any other .net languages for that matter.
First of all I want to be able to create a library that has the following function HelloWorld that takes this parameter:
Name
In C# the method signature would looke like this: void HelloWorld(string name) and it would print out something like
Hello World from name
I've searched around a bit but can't find that much good and clean material for this to get me started. I know some basic assembly from before mostly gasthough.
So any pointers in the right direction is very much apprechiated.
To sum it up
Create a function in ASM ( NASM ) that takes one or more parameters
Compile and create a library of the above functionality
Include the library in any .net language
Call the included library function
Bonus features
How does one handle returned values?
Is it possible to write the ASM-method inline?
When creating libraries in assembly or c, you do follow a certain "pre defined" way, the c calling convetion, correct?
