Well, it's true in Boolean context but 0 in numeric context. Looking through the docs on fcntl, it looks like it's useful for the Perl calls that are wrappers to C system calls.

For example, if fcntl returns -1 to signify failure, Perl will massage that into undef. If it returns 0, Perl will use "0 but true" -- which means you can use it either numerically (C-style, expecting 0 to correspond to success) or Booleanifically (Perl-style, expecting 'true' to mean success).

Close enough?
