May I respectfully suggest error-checking:

     if (putc(c, fp2) == EOF)
	... handle error ...

And yes, even fclose!

     if (fclose(fp1) == EOF)
	... handle error ...

It seems like overkill, but not detecting a full device is a *very*
common bug in C programs.  (However, a possible optimization is to call
ferror() just once before the output stream is closed instead of
testing the value from putc all the time.)
