Function

GLibPtrArraynew_from_array

since: 2.76

Declaration [src] 

GPtrArray*
g_ptr_array_new_from_array (
  gpointer* data,
  gsize len,
  GCopyFunc copy_func,
  gpointer copy_func_user_data,
  GDestroyNotify element_free_func
)

Description [src]

Creates a new GPtrArray, copying len pointers from data, and setting the array’s reference count to 1.

This avoids having to manually add each element one by one.

If copy_func is provided, then it is used to copy each element before adding them to the new array. If it is NULL then the pointers are copied directly.

It also sets element_free_func for freeing each element when the array is destroyed either via g_ptr_array_unref(), when g_ptr_array_free() is called with free_segment set to TRUE or when removing elements.

Do not use it if len is greater than G_MAXUINT. GPtrArray stores the length of its data in #guint, which may be shorter than

gsize.

Available since: 2.76

This function is not directly available to language bindings.

Parameters

data

Type: An array of gpointer

An array of pointers, or NULL for an empty array.

The argument can be NULL.
The length of the array is specified in the len argument.
The data is owned by the caller of the function.
len

Type: gsize

The number of pointers in data.

copy_func

Type: GCopyFunc

A copy function used to copy every element in the array or NULL.

copy_func_user_data

Type: gpointer

User data passed to copy_func, or NULL.

The argument can be NULL.
The data is owned by the caller of the function.
element_free_func

Type: GDestroyNotify

A function to free elements on array destruction or NULL.

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.
