<h2><a name="Special_Purpose_NCI_Parameter_Types"
>Special Purpose NCI Parameter Types</a></h2>
<p>The NCI parameter types 'J',
'@',
't',
'0',
'V',
'2',
'3',
'4',
'B',
'b',
'L',
and 'T' have been removed.</p>
<h3><a name="Rationale"
>Rationale</a></h3>
<p>These types are special-purpose and their function can be accomplished by other means.</p>
<h3><a name="Replacement"
>Replacement</a></h3>
<h4><a name="'J',_'@',_'t',_'0'"
><b>'J',
'@',
't',
'0'</b></a></h4>
<p>These types accomplish tasks which can be accomplished from PIR and are therefore redundant</p>
<dl>
<dt><a name="'J'"
>'J'</a></dt>
getinterp + pointer NCI types
<dt><a name="'@'"
>'@'</a></dt>
slurpy param on a wrapping PIR sub
<dt><a name="'t'"
>'t'</a></dt>
manual lifetime management of C string buffer through NCI access to Parrot_str_to_cstring() and Parrot_str_free_cstring()
<dt><a name="'0'"
>'0'</a></dt>
null + pointer NCI type</dl>
<h4><a name="'V',_'2',_'3',_'4',_'B'"
><b>'V',
'2',
'3',
'4',
'B'</b></a></h4>
<p>A less type-specific pass-by-reference mechanism is available.</p>
<p>See the bindings for pcre_compile() in runtime/parrot/library/pcre.pir for an example of its use.</p>
<h4><a name="'b',_'L',_'T'"
><b>'b',
'L',
'T'</b></a></h4>
<p>These were poorly documented and were broken in their implementation.
No replacement has been provided as these do not represent desirable behaviour.</p>
