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