The prime purpose of a GValueArray is for it to be used as an
object property that holds an array of values. A GValueArray wraps
an array of GValue elements in order for it to be used as a boxed
type through G_TYPE_VALUE_ARRAY.
typedef struct {
  guint   n_values;
  GValue *values;
} GValueArray;
A GValueArray contains an array of GValue elements.
GValue* g_value_array_get_nth (GValueArray *value_array, guint index_);
Return a pointer to the value at index_ containd in value_array.
| 
 | GValueArray to get a value from | 
| 
 | index of the value of interest | 
| Returns : | pointer to a value at index_invalue_array | 
GValueArray* g_value_array_new (guint n_prealloced);
Allocate and initialize a new GValueArray, optionally preserve space
for n_prealloced elements. New arrays always contain 0 elements,
regardless of the value of n_prealloced.
| 
 | number of values to preallocate space for | 
| Returns : | a newly allocated GValueArray with 0 values | 
GValueArray* g_value_array_copy (const GValueArray *value_array);
Construct an exact copy of a GValueArray by duplicating all its contents.
| 
 | GValueArray to copy | 
| Returns : | Newly allocated copy of GValueArray | 
void g_value_array_free (GValueArray *value_array);
Free a GValueArray including its contents.
| 
 | GValueArray to free | 
GValueArray* g_value_array_append (GValueArray *value_array, const GValue *value);
Insert a copy of value as last element of value_array.
| 
 | GValueArray to add an element to | 
| 
 | GValue to copy into GValueArray | 
| Returns : | the GValueArray passed in as value_array | 
GValueArray* g_value_array_prepend (GValueArray *value_array, const GValue *value);
Insert a copy of value as first element of value_array.
| 
 | GValueArray to add an element to | 
| 
 | GValue to copy into GValueArray | 
| Returns : | the GValueArray passed in as value_array | 
GValueArray* g_value_array_insert (GValueArray *value_array, guint index_, const GValue *value);
Insert a copy of value at specified position into value_array.
| 
 | GValueArray to add an element to | 
| 
 | insertion position, must be <= value_array->n_values | 
| 
 | GValue to copy into GValueArray | 
| Returns : | the GValueArray passed in as value_array | 
GValueArray* g_value_array_remove (GValueArray *value_array, guint index_);
Remove the value at position index_ from value_array.
| 
 | GValueArray to remove an element from | 
| 
 | position of value to remove, must be < value_array->n_values | 
| Returns : | the GValueArray passed in as value_array | 
GValueArray* g_value_array_sort (GValueArray *value_array, GCompareFunc compare_func);
Sort value_array using compare_func to compare the elements accoring to
the semantics of GCompareFunc.
The current implementation uses Quick-Sort as sorting algorithm.
| 
 | GValueArray to sort | 
| 
 | function to compare elements | 
| Returns : | the GValueArray passed in as value_array | 
GValueArray* g_value_array_sort_with_data (GValueArray *value_array, GCompareDataFunc compare_func, gpointer user_data);
Sort value_array using compare_func to compare the elements accoring
to the semantics of GCompareDataFunc.
The current implementation uses Quick-Sort as sorting algorithm.
| 
 | GValueArray to sort | 
| 
 | function to compare elements | 
| 
 | extra data argument provided for compare_func | 
| Returns : | the GValueArray passed in as value_array |
