Thread: Copying Files

Check the above, it is for copying files.

So my question is : Using an int for copying, is it safe for every file e.x. mp3's pdf's etc. Or is there another way such as byte (bit) copy just for safety ?

Code:

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

static FILE *open_file ( char *file, char *mode )
{
  FILE *fp = fopen ( file, mode );

  if ( fp == NULL ) {
    perror ( "Unable to open file" );
    exit ( EXIT_FAILURE );
  }

  return fp;
}

int main ( int argc, char *argv[] )
{
  int ch;
  FILE *in;
  FILE *out;

  if ( argc != 3 ) {
    fprintf ( stderr, "Usage: %s <readfile1> <writefile2>\n", argv[0] );
    exit ( EXIT_FAILURE );
  }

  in = open_file ( argv[1], "r" );
  out = open_file ( argv[2], "w" );

  while ( ( ch = fgetc ( in ) ) != EOF )
    fputc ( ch, out );

  fclose ( in );
  fclose ( out );

  return EXIT_SUCCESS;
}
