```{index} single: hash; B function ``` ```{index} single: B::hash; Perl function ``` # hash Return perl's hash of a string, formatted as `0xNNNNNNNN`. ## Synopsis ```perl my $h = B::hash("foo"); # e.g. "0x2ad53e4d" ``` Uses the same hash function the interpreter uses for hash keys, so the value is useful for reasoning about bucket placement and hash collisions in a live hash, not as a general-purpose checksum.
