Name
return
Synopsis
return expr
Returns from a subroutine (or eval) with the value of
expr. (In the absence of an explicit
return, the value of the last
expression evaluated is returned.) Use of return outside of a subroutine or
eval will result in a fatal
error.
The supplied expression will be evaluated in the context of
the subroutine invocation. That is, if the subroutine was called
in a scalar context, expr is also
evaluated in scalar context. If the subroutine was invoked in a
list context, then expr is also
evaluated in list context and can return a list value. A return
with no argument returns the undefined value in scalar context and
a null list in list context. The context of the subroutine call
can be determined from within the subroutine by using the
(misnamed) wantarray
function.
