Odd programming question

[trekiej]

Outside of header files and libraries, when does OS specific information get added?
When I run a programm, how does  the OS allocate memory and give control to the application and the application give it back.
The OS gives the application access to resources, how does it know what to give?
Source > Object > linking > Binary

Thanks alot.  I want to know more about OS and Application interactivity.

I guess I need to find out how a kernel works to get the info. in need.  As CSI Grissom would say, I am looking for the right question.

I know I have asked a similar question before and it led to System Calls.  I want to know how my application gets to the real world and there seems to be more than one answer.

What I wish I could do is learn how to use the header files and libraries to make a window to put my app.
Right now making a console app on an Amiga will do.
I wish they would teach Amiga Dos in college.

I feel like there is information added during compile time that the user does not have to provide.

@ Piru:
Maybe that is what gets me.   :-D
Learning C in an intro class we used include iostream.h to get I/O.
How does iostream.h work?

Alright, thanks.
I will put this on the back burner.
I will look into how to work with libraries, etc.
I can not seem to get my c++ finished.  I guess I can still work with the Amiga without it.

Is making a basic console program easy to do?

[trekiej]

For Amiga, nothing.  I am looking to use StormC.
GCC for linux.
AmiDevCPP for widows. (AROS)
Murks IDE

@Samurai Crow
Looks like you are working on something interesting.
Also, when the program gets changed to binary is there anything else the compiler does?

@Trev
Sure I knew that about AmiDev. :oops:

Thanks

Compiler, linker, assembler are not a problem.  It is how the OS looks at and responds to the program.  I wish I had a explanation of all that happens when a program loads.  This is imo different for different OS.

[trekiej]

I appreciate all replies.

In the end I guess I will need to get into Kernel Dev to get the full understanding.

On a side note, do files have headers.  I do not mean xxx.h in a C program.  Is this not how an OS knows the difference between files?
@Karlos:
That is where I want to head with this.  I may get into Kernel Dev. with Linux but may go a non-programming route with my career.

@Einstein: Maybe one day I will.  I have too much to do and need a job to go further.  I have a part-time job but it is not enough.  I like too much technology and need to pick one and go with it.
