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.
