GLib.PtrArray.new_null_terminated
Description: Reference for GLib.PtrArray.new_null_terminated

### Function

# GLib PtrArraynew_null_terminated

since: 2.74

#### Declaration

    GPtrArray*
    g_ptr_array_new_null_terminated (
      guint reserved_size,
      GDestroyNotify element_free_func,
      gboolean null_terminated
    )

#### Description

Like `g_ptr_array_new_full()` but also allows to set the array to be `NULL` terminated. A `NULL` terminated pointer array has an additional `NULL` pointer after the last element, beyond the current length.

`GPtrArray` created by other constructors are not automatically `NULL` terminated.

Note that if the `array`‘s length is zero and currently no data array is allocated, then pdata will still be `NULL`. %GPtrArray will only `NULL` terminate pdata, if an actual array is allocated. It does not guarantee that an array is always allocated. In other words, if the length is zero, then pdata may either point to a `NULL` terminated array of length zero or be `NULL`.

Available since: 2.74

This function is not directly available to language bindings.

#### Parameters

`reserved_size`

  Type: `guint`

  Number of pointers preallocated. If `null_terminated` is `TRUE`, the actually allocated buffer size is `reserved_size` plus 1, unless `reserved_size` is zero, in which case no initial buffer gets allocated.

`element_free_func`

  Type: `GDestroyNotify`

  A function to free elements with destroy `array` or `NULL`.

`null_terminated`

  Type: `gboolean`

  Whether to make the array as `NULL` terminated.

#### Return value

Type: An array of `gpointer`

A new `GPtrArray`.

The caller of the function takes ownership of the data, and is responsible for freeing it.
