Copy function?

[Wynd]

Is there a copy function in C++? Currently I am using system("copy a b") but this prints out "x file(s) copied" which I don't want. Any ideas?

Write your own:

int copy(char* f1, char* f2)
{
   FILE* fp1 = NULL;
   FILE* fp2 = NULL;
   fp1 = fopen(f1, "w+b");
   fp2 = fopen(f2, "wb");
   unsigned long flen;
   fseek(fp1, SEEK_END, 0);
   flen = ftell(fp1);
   char t;
   unsigned long i = 0;
   while(i <= flen)
   {
         fread(&t, 1, 1, fp1);
         fwrite(&t, 1, 1, fp2);
   }
   fclose(fp1);
   fclose(fp2);
}

Off the top of my head, but it should work. You could speed it up by grabbing perhaps 500k chuncks at a time, instead of a single byte, but Ill leave that up to you =).

WinAPI has CopyFile.

Zaei: Doesn't work, all I ended up with was a 3MB file
CornedBee: I'd prefer not to use the API. I am trying to not go platform-dependent.

You should be able to fifure it out...

The problem is that you're at the end of the file...
Add a rewind(fp1); before reading data.
And I'd open it in pure read mode (rb), not read/write.

It was midnight... thats my only excuse =).

Ok, I tried writing this:

void copy(const char* srcpath, const char* destpath)
{
    FILE* src = fopen(srcpath, "rb");
    FILE* dest = fopen(destpath, "wb");
    char t;

    while (!feof(src))
    {
        t = fgetc(src);
        fputc(t, dest);
    }

    fclose(src);
    fclose(dest);
}

Works fine, except it prints ÿ at the end of the new file. Where's it coming from and how can I fix it?
