## Detailed Description

## Typedef Documentation

## ◆ Eina_Value_List

Eina_Value_List

Value type for EINA_VALUE_TYPE_LIST.

See also
  _Eina_Value_List explains fields.

Since
  1.2

## Function Documentation

## ◆ eina_value_list_new()

EINA_API Eina_Value * eina_value_list_new | ( | const Eina_Value_Type * | subtype | ) |

Creates generic value storage of type list.

Parameters

  [in] | subtype | How to manage this list members.

Returns
  The new value, or `NULL` on failure.

Create a new generic value storage of type list. The members are managed using the description specified by subtype.

On failure, `NULL` is returned.

Note
  this creates from mempool and then uses eina_value_list_setup().

## ◆ eina_value_list_setup()

static Eina_Bool eina_value_list_setup | ( | Eina_Value * | value,
|  | const Eina_Value_Type * | subtype
| ) |  |
| inlinestatic

Initializes generic value storage of type list.

Parameters

  [out] | value | Value object
  [in] | subtype | How to manage this list members.

Returns
  EINA_TRUE on success, EINA_FALSE otherwise.

Initializes new generic value storage of type list with the given subtype.

This is the same as calling eina_value_set() with EINA_VALUE_TYPE_LIST followed by eina_value_pset() with the Eina_Value_List description configured.

Note
  Existing contents are ignored! If the value was previously used, then use eina_value_flush() first.

On failure, EINA_FALSE is returned.
