Subject: QDict: Introduce functions to retrieve QDictEntry values
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=0d078b2adec72fd74b00defb260724b33e87e184;p=qmiga%2Fqemu.git

QDict: Introduce functions to retrieve QDictEntry values

Next commit will introduce a new QDict iteration API which
returns QDictEntry entries, but we don't want users to directly
access its members since QDictEntry should be private to QDict.

In the near future this kind of data type will be turned into a
forward reference.
