<h1><a name="DESCRIPTION"
>DESCRIPTION</a></h1>
<p>Freezes other PMCs.</p>

<dl>
<dt><a name="static_opcode_t_*_GET_VISIT_CURSOR(const_PMC_*pmc)"
><b><code>static opcode_t * GET_VISIT_CURSOR(const PMC *pmc)</b></code></a></dt>
Get the buffer cursor.
Buffer relocations are handled.
<dt><a name="static_void_SET_VISIT_CURSOR(PMC_*pmc,_const_char_*cursor)"
><b><code>static void SET_VISIT_CURSOR(PMC *pmc, const char *cursor)</b></code></a></dt>
Set the buffer cursor.
Buffer relocations are handled.
<dt><a name="static_void_INC_VISIT_CURSOR(PMC_*pmc,_UINTVAL_inc)"
><b><code>static void INC_VISIT_CURSOR(PMC *pmc, UINTVAL inc)</b></code></a></dt>
Increment the buffer cursor.
Buffer relocations are handled.
<dt><a name="static_void_create_buffer(PARROT_INTERP,_PMC_*pmc,_PMC_*info)"
><b><code>static void create_buffer(PARROT_INTERP, PMC *pmc, PMC *info)</b></code></a></dt>
Allocate the image buffer.
<dt><a name="static_void_ensure_buffer_size(PARROT_INTERP,_PMC_*io,_size_t_len)"
><b><code>static void ensure_buffer_size(PARROT_INTERP, PMC *io, size_t len)</b></code></a></dt>
Checks the size of the buffer to see if it can accommodate <code>len</code> more bytes.
If not,
expands the buffer.
<dt><a name="static_UINTVAL_check_seen(PARROT_INTERP,_PMC_*self,_PMC_*v)"
><b><code>static UINTVAL check_seen(PARROT_INTERP, PMC *self, PMC *v)</b></code></a></dt>
Check the seen hash to prevent duplicate serialization.</dl>
<h1><a name="VTABLES"
>VTABLES</a></h1>
<dl>
<dt><a name="void_init()"
><b><code>void init()</b></code></a></dt>
Initializes the PMC.
<dt><a name="void_destroy()"
><b><code>void destroy()</b></code></a></dt>
Destroys the PMC.
<dt><a name="void_mark()"
><b><code>void mark()</b></code></a></dt>
Marks the PMC as alive.
<dt><a name="STRING_*get_string()"
><b><code>STRING *get_string()</b></code></a></dt>
Returns the content of the image as a string.
<dt><a name="void_*get_pointer()"
><b><code>void *get_pointer()</b></code></a></dt>
Returns the seen hash.
<dt><a name="VTABLE_INTVAL_get_integer()"
><b><code>VTABLE INTVAL get_integer()</b></code></a></dt>
Returns the flags describing the visit action.
<dt><a name="VTABLE_void_push_integer(INTVAL_v)"
><b><code>VTABLE void push_integer(INTVAL v)</b></code></a></dt>
Pushes the integer <code>v</code> onto the end of the image.
<dt><a name="VTABLE_void_push_float(FLOATVAL_v)"
><b><code>VTABLE void push_float(FLOATVAL v)</b></code></a></dt>
Pushes the float <code>v</code> onto the end of the image.
<dt><a name="VTABLE_void_push_string(STRING_*v)"
><b><code>VTABLE void push_string(STRING *v)</b></code></a></dt>
Pushes the string <code>*v</code> onto the end of the image.
<dt><a name="VTABLE_void_push_pmc(PMC_*v)"
><b><code>VTABLE void push_pmc(PMC *v)</b></code></a></dt>
Pushes a reference to pmc <code>*v</code> onto the end of the image.
If <code>*v</code> hasn't been seen yet,
it is also pushed onto the todo list.
<dt><a name="void_set_pointer(void_*value)"
><b><code>void set_pointer(void *value)</b></code></a></dt>
Sets the constant table of this ImageIO PMC.</dl>
