[Xfce-i18n] Request: Definition of 'initialize' in a string

[Kristjan Siimson]

Hello,

I am translating the following string:
"Failed to initialize xfconf. Reason: %s"

Wiktionary gives following definitions for 'initialize'. Which one, if
any, is the correct definition. If not any, may someone give me the
correct definition?

* To assign initial values to something
* (computing) To assign an initial value to a variable
* (computing) To format a storage medium prior to use
* (computing) To prepare any hardware (such as a printer or scanner) for use

http://en.wiktionary.org/wiki/initialize

Sincerely,
Kristjan Siimson
