<h1><a name="NAME"
>NAME</a></h1>
<p>src/pmc/nci.pmc - Native Call Interface</p>
<h1><a name="DESCRIPTION"
>DESCRIPTION</a></h1>
<p>The vtable functions for the native C call functions.</p>
<h2><a name="Methods"
>Methods</a></h2>
<dl>
<dt><a name="static_nci_thunk_t_build_func(PARROT_INTERP,_Parrot_NCI_attributes_*nci)"
><b><code>static nci_thunk_t build_func(PARROT_INTERP, Parrot_NCI_attributes *nci)</b></code></a></dt>
Actually build the NCI thunk.
<dt><a name="METHOD_get_multisig()"
><b><code>METHOD get_multisig()</b></code></a></dt>
Return the MMD signature PMC,
if any or <code>PMCNULL</code>.
<dt><a name="void_init()"
><b><code>void init()</b></code></a></dt>
Initializes the NCI with a <code>NULL</code> function pointer.
<dt><a name="void_set_pointer_keyed_str(STRING_*key,_void_*func)"
><b><code>void set_pointer_keyed_str(STRING *key, void *func)</b></code></a></dt>
Sets the specified function pointer and signature (<code>*key</code>).
<dt><a name="void_mark()"
><b><code>void mark()</b></code></a></dt>
Mark any referenced strings and PMCs.
<dt><a name="PMC_*clone()"
><b><code>PMC *clone()</b></code></a></dt>
Creates and returns a clone of the NCI.
<dt><a name="INTVAL_defined()"
><b><code>INTVAL defined()</b></code></a></dt>
Returns whether the NCI is defined.
<dt><a name="opcode_t_*invoke(void_*next)"
><b><code>opcode_t *invoke(void *next)</b></code></a></dt>
Calls the associated C function,
returning <code>*next</code>.
If the invocant is a class,
the PMC arguments are shifted down.
<dt><a name="INTVAL_get_integer()"
><b><code>INTVAL get_integer()</b></code></a></dt>
Returns the function pointer as an integer.
<dt><a name="INTVAL_get_bool()"
><b><code>INTVAL get_bool()</b></code></a></dt>
Returns the boolean value of the pointer.
<dt><a name="METHOD_arity()"
><b><code>METHOD arity()</b></code></a></dt>
Return the arity of the NCI (the number of arguments).</dl>
