arrays of arbitrary elements which grow automatically as elements are added

Arrays are similar to standard C arrays, except that they grow automatically
|

as elements are added.

</para>
|

<para>
|

Array elements can be of any size (though all elements of one array are the
|
||||
same size), and the array can be automatically cleared to '0's and
|
||||
zero-terminated.

</para>

|
||||
To create a new array use g_array_new().

<para>

To add elements to an array, use g_array_append_val(), g_array_append_vals(),

g_array_prepend_val(), and g_array_prepend_vals().

<para>

To access an element of an array, use g_array_index().

To set the size of an array, use g_array_set_size().

To free an array, use g_array_free().

Removes the element at the given index from a #GArray.

Sorts a #GArray using @compare_func which should be a qsort()-style comparison

function (returns less than zero for first arg is less than second arg,

zero for equal, greater zero if first arg is greater than second arg).

The return value is cast to the given type.

<!-- ##### FUNCTION g_array_set_size ##### -->
|

<para>
|

Sets the size of the array, expanding it if necessary.

If the array was created with @clear_ set to %TRUE, the new elements are set to 0.
|

</para>
|
||||
|

@array: a #GArray.

@length: the new size of the #GArray.

@Returns: the #GArray.
|
||||
|
||||
|
||||
<!-- ##### FUNCTION g_array_free ##### -->
|
||||
<para>
|
||||
Frees the memory allocated for the #GArray.
|
||||
If @free_segment is %TRUE it frees the memory block holding the elements
|
||||
as well and also each element if @array has a @element_free_func set.
|
||||
Pass %FALSE if you want to free the #GArray wrapper but preserve
|
||||
the underlying array for use elsewhere. If the reference count of @array
|
||||
is greater than one, the #GArray wrapper is preserved but the size of
|
||||
@array will be set to zero.
|
||||
</para>
|
||||
<note>
|
||||
<para>
|
||||
If array elements contain dynamically-allocated memory, they should be freed
|

separately.
|
||||
</para>
|
||||
</note>
|
||||
|
||||
@array: a #GArray.
|
||||
@free_segment: if %TRUE the actual element data is freed as well.
|
||||
@Returns: the element data if @free_segment is %FALSE, otherwise %NULL.
|
||||
The element data should be freed using g_free().

|

If you remove elements from the array, elements at the end of the array
|

are moved into the space previously occupied by the removed element.
|
||||
This means that you should not rely on the index of particular elements
|
||||
remaining the same. You should also be careful when deleting elements while
|
||||
iterating over the array.

* To create a new array use g_array_new().
