I can't make sense of your question. If myfunction() returns a filehandle, then it is out of place in an expression like 

print FILEHANDLE myfunction();

unless you want your output to look something like GLOB(0x1234567).

I think that what you want is something like 

my $output_handle = myfunction();
if ( $output_handle ) {
  print $output_handle $whatever;
}
else {
  # deal with null-handle error
}
