https://metacpan.org/pod/Inline::C-Cookbook has lots of good examples. But I can't find an example on implementing a C function which takes a perl string (may contain binary characters such as \x00 in the string) and return another perl string (with binary characters).
In another word, the C function should have the similar syntax as the
following perl function.
sub myRepeat {
my $str = shift;
return $str . $str;
}
Thank in advance.
