sub

Perl functions A-Z | Perl functions by category | The 'perlfunc' manpage
  • sub NAME BLOCK

  • sub NAME (PROTO) BLOCK
  • sub NAME : ATTRS BLOCK
  • sub NAME (PROTO) : ATTRS BLOCK

    This is subroutine definition, not a real function per se. Without a BLOCK it's just a forward declaration. Without a NAME, it's an anonymous function declaration, so does return a value: the CODE ref of the closure just created.

    See perlsub and perlref for details about subroutines and references; see attributes and Attribute::Handlers for more information about attributes.
