Then I guess we have a misunderstanding here.

To me it reads as if you want to use the exec-function but don't know which header file you use. If that's the case then `man` will help you. I just tried it and these are the first lines I got:

so, as you can see, exec() needs the the unistd.h-file included.

----------------

If that's not the case then you might want to post the question more specific.

What do you want to program, a graphical application? Then have a look at QT, GtK+ or wxwindows. A console application then see if a bash/perl/python/tsh/csh or other script languages there are, if they're not enough, there are Linux compilers for C,C++, Java, Fortran, Pascal and hundreds of others languages (well, except for C# maybe ) out there that may suit your needs. If you want to do some driver development your first look might go into /usr/src/linux/Documentation .... the possibilities are endless and that's why it's so difficult to answer your question.

So guys, don't flame each other. This guy's a coder as we all are

Hello,

I have C++ and I come from windows. Windows has a base API not just for the GUI but for basic operation like the exec() function....

I want to learn the linux base API (if there is on) and where I can locate the API... I do not want to learn a GUI API right now....

So heres my question:
Dose linux have a base API other than a GUI's API, or dose it just use the std files (stdio.h and such)? If the first option is right where can I get them and learn it?

Thanks,
Andrew

If you are programming in C++ a good place to start looking about libraries is here:
http://gcc.gnu.org/onlinedocs/libstd...mentation.html

That is the documentation for the GNU C++ Standard Library which is what I would consider the standard application interface for a linux C++ program. It works in conjunction with gcc which is the standard compiler most people use.


I am not sure how good a job they do, but they try and talk about the differences between how gcc does C++ vs. other implementations people are used to using. I have only ever done C++ with gcc so that didn't mean much to me personally and I skipped it.

Ok thank you very much!

Andrew

oh so you know all the 80,000 some winapi functions?

Depends what you are looking for.

I guess, that you know C++. Else you wouldnt ask about the API for linux (C++ classes)
Therefor I guess its not reference documentation for the language itself you need.
As some people pointed out theres online references to the language C++ and C on gnu.org

Linux does not have a foundation C++ library, if you looking for a foundation library for linux I would have to dispoint you. Most of Linux (and Unix) is coded in C. And the man pages are the place to look for documentation of specific functions. However learning from the man pages alone is not easy, and you should get a good book teaching Unix API. Linux follows (most of) the Unix API (A table of Unix API function calls can be found at www.unix.org). I would recomend a book here, but.. It actualy slipped my mind. You could however get _any_ Unix-C-Api book out there, it does not have to be Linux specific. If anything missmatches then refere to the man pages. By the way, the man pages are installed when you install the development enviroment on Linux (This is normaly included in every distribution of Linux.. RedHat, Suse, Debian).

Did a search on google, and I think this could be a good book for you: "Advanced Programming in the UNIX Environment" (http://www.amazon.co.uk/exec/obidos/...348230-1206259).

These APIs does not include any GUI stuff at all !!!! Unix is very "down to basics" and to code GUI you need to use one of the many GUI libraries around (GTK, Xt, etc..).

If you do not want to learn C, and if you are stuck in classes theres libraries thats "ontop" of the Unix-System(C)-Api. These libraries might be what you looking for if you want to getup to speed in development under Linux. wxWindows.org is one of these, its a GUI library but it also includes socket handling, for normaly file handling you can use the normal C++ language API.

Both C and C++ compilers are installed if you install the development enviorment when installing Linux on your box. You can find the includefiles in diffrent locations on the machine, most common are /usr/include, /usr/X11R6/include and /usr/local/include. The C manual you find using the man pages "man socket". The howtos you find in general Unix books, as IDE (integrade development enviroment) (think VisualStudioC++) you can use KDevelop (www.kde.org).

Hope this helped some, and that I didnt get what you wanted wrong =)

You can also try out the libraries that come with linux like Qt or GTK+. They cover every API that is in Windows, and you don't need to look for any other API's when you use them!

No I do not know ALL the win32 functions but I know what I need...

I was using Win32 API as an exapmle....

Worldmagic, thank you or response hit it on the head... I tried goggling but I was googling the Wong term and I found nothing...

This is why I asked...

I have programed in wrappers like WxWindows and SDL and I don't seem to like the resutels...

Thanks A Again!

Andrew

Just a thought...

You needn't be so rude.. he merely asked where to learn them..he didnt say anything about knowing all the winapi functions... if you cant post something helpful or nice... then dont post... LQ.org is not about flaming others...if you cant help or dont want to... dont post...simple as that.
