NAME FFI::Platypus::Record::StringArray - Array of strings for your FFI record VERSION version 0.01 SYNOPSIS my $a = FFI::Platypus::Record::StringArray->new(qw( foo bar baz )); my $opaque = $a->opaque; DESCRIPTION Experimental interface for an array of C strings, useful for FFI record classes. The Platypus record class doesn't easily support an array of strings, and trying to use an opaque type to implement this is possible but more than a little arcane. This class provides an interface for creating a C array of strings which can be used to provide an opaque pointer than can be used by an FFI::Platypus::Record object. Care needs to be taken! Because Perl has no way of knowing if/when the opaque pointer is no longer being used by C, you have to make sure that the FFI::Platypus::Record::StringArray instance remains in scope for as long as the opaque pointer is in use by C. CONSTRUCTOR new my $a = FFI::Platypus::Record::StringArray->new(@a); Creates a new array of C strings. METHODS opaque my $opaque = $a->opaque; Returns the opaque pointer to the array of C strings. size my $size = $a->size; Returns the number of elements in the array of C strings. element my $element = $a->element($index); Returns the string in the array of C strings at the given index.
