Copy audio file using C?

[vino4all]

Hi,
I'm a newbie............ Sorry, if I violate any norms.

Is it possible to copy any audio file or image file using C language? I think it is possible. If anyone knows it please guide me.
If you know the code, that 'll be helpful.

you can copy any file, whatever the type or extension.

just open the source file as a binary file and use a while loop to copy each byte one at a time to the destination, until the EOF charater is found.

see fopen(), fgetc(), fputc(), and feof() in the standard C library <stdio.h>. that's all the functions you'll need, though you'll probably want to include error checking with ferror().

copying byte by bye using loop...uh...sounds like a complected process...:|

uh... not so much :)

#include <stdio.h>
#include <stdlib.h>

int main(int argc, char **argv)
{
   FILE *fp_source, *fp_dest;
   char oneByte;

   /* WARNING:  this does ZERO error checking!! */

   fp_source = fopen(argv[1], "rb"));
   fp_dest   = fopen(argv[2], "wb"));

   while(!feof(fp_source)) {
      oneByte = fgetc(fp_source);
      fputc(oneByte, fp_dest);
   }

   fclose(fp_source);
   fclose(fp_dest);

   return 0;
}

How about stopping the loop without the !eof() ? eof() is not a good solution as the exit control of a loop. EOF would be true only after it is read and not when it is reached. char oneByte; must be an int, since fgetc() returns an int, and it is not a guarantee that char would be signed.

geez...i should read pointers and file data handling before understanding it properly.

That sounds good dude......

Working nicely. Thanks a lot

you're right about the byte should be type int, not char. it may possibly fail for some compilers. i don't know why i keep doing that, i know better.

however, i disagree with you about the eof() .. i think that's a valid way to exit the loop. unless you can remind me why it's not.

A `reminder'
