problem with fgetc and getc and file reading

I open a file with fopen, and fgetc and getc won't read the value of 0x0d from the file. It acts like it's not even there and moves on to the next value instead. For example, if there is the newline values( 0x0d, 0x0a) in the file, and I try to read the 0x0d, it will read the 0x0a instead of it.

//Functions getc and fgetc are text-oriented.
//The best (and fastest) solution to open file as binary,
//use buffered reading (function fread) and handle this
//buffer as you want.

//Example following:

int format_to_one_line(char * input_name, char * output_name)
{
    if ((fin=fopen(input_name,"rb"))==NULL) return 2;
    if ((fout=fopen(output_name, "wb+"))==NULL) return 3;
    //------------------------------
    while (!feof(fin))
    {
        blocksize = fread(bufin,1,BUFSIZE,fin);
        j=0;
        if (blocksize)
        {
           for (i=0;i<blocksize;i++)
           {
               if (bufin[i]==0x0D)
               {
                  //delete CR/LF or LF/CR
                  if (bufin[i+2]!=' ' &&
                      bufin[i+2]!=0x0D &&
                      i<(blocksize-2) &&
                      bufin[i+2]!=0x09 && //TAB
                      !isdigit(bufin[i+2]))
                      {
                         i+=2; //Skip it
                         bufout[j++]=' ';
                      }

               }
               bufout[j++]=bufin[i];
           }
           if (fwrite(bufout,1,j,fout)<j) return 3;
        }
    }
    //------------------------------
    fclose(fin);
    fclose(fout);
    return 0;
}
