What's wrong ?

I'm writting C++ program, I have KANOTIX, g++ . When I try to compile

Code:

main() 
{
CopyFile("~/Desktop/what.txt, "~/Dekstop/what3.txt", false);
}

g++ "says" to me :

Quote:

cooldude.c: In function `int main()':
copy.c:3: error: `Dekstop' undeclared (first use this function)
copy.c:3: error: (Each undeclared identifier is reported only once for each
function it appears in.)
copy.c:3: error: `what3' undeclared (first use this function)
copy.c:3:49: missing terminating " character
copy.c:4: error: parse error before string constant

Can somebody "translate" this to me? What should I do?

You are missing a closing quote for your first parameter
Are you sure you want to copy from the Desktop folder to Dekstop? Looks like a typo there
Because the ~ expansion is a bash thing, i don't think your C program is going to expand that to /home/username for you. You may need to supply a full path.
Edit: It also appears you are trying to use the Win32 CopyFile function. That's not in the standard C/C++ library. Since you are using Linux, it's not even in one of the typical Linux libraries. You can however, probably install the Wine libraries and use those. (Although, if the only Win32 function you want to use is CopyFile, there are probably better ways to do it than using Winelib just for that...)

Your missing a closing quotation for the first argument to 'CopyFile'.

Is there any other way to copy file in linux ?

The cp command is the easiest way to copy a file.

If you want to copy a file through a C program, you could either do it manually by opening it up, reading, and then writing it out to another file or use the system function:
system("cp ~/Desktop/what.txt ~/Dekstop/what3.txt");

I wanted to make file that can copy itself into ~/.kde/Autostart . How can I do that?

Many ways.

Code:

cp filea fileb
cat filea >fileb
cat <filea >fileb
sed '' filea >fileb
dd if=filea of=fileb
echo "$(<filea)" >fileb
awk '{print}' filea >fileb
awk '//' filea >fileb

cp is the most obvious, though.

Well, if you really want a file to copy itself (you still have to execute it, though):

Code:

#!/bin/more +2 ~/.kde/Autostart
Put the wanted
file contents in the rest of the
file, make it executable with
chmod a+x thisfile'sname
and then execute it

will copy all but the first line into ~/.kde/Autostart. I'm not sure this is really what you mean, though, is it?

Yeah, that is what I really mean but how to do it? gimme code
