DESCRIPTION¶

This class represents an instance of a C "struct". This class can be created using "new" on the generated class, if that was specified for the FFI::C::StructDef, or by using the "create" method on FFI::C::StructDef.

For each member defined in the FFI::C::StructDef there is an accessor for the FFI::C::Struct instance.

CONSTRUCTOR¶

 FFI::C::StructDef->new( class => 'User::Struct::Class', ... );
 my $instance = User::Struct::Class->new;
