Requests the value appropriate for a particular locale. Right now,

Asks whether a key is syntactically correct, that is, it ensures that
the key consists of slash-separated strings and contains only legal
characters. Normally you shouldn't need to call this function; the
GConf functions all check this for you and return an error if the key
is invalid. However, it may be useful to validate input to an entry
field or the like. If you pass a non-<span class="symbol">NULL</span> address as
the <em class="parameter"><code>why_invalid</code></em> argument, an allocated string is returned explaining
why the key is invalid, if it is. If the key is valid the <em class="parameter"><code>why_invalid</code></em>
argument is unused.

<p>
It's best to store enumeration values as strings rather than integers. This is
robust against changes in the enumeration, and also human-readable.
This function makes it more convenient to store enums as strings.
</p>
<p>
The first argument is a lookup table, typically declared statically as follows:
</p>
<pre class="programlisting">
static GConfEnumStringPair foo_enum_lookup_table[] = {
{ FOO_BLAH, "Blah" },
{ FOO_BAR, "Bar" },
{ 0, NULL }
};
</pre>
<p>
Note that the last element of the table is <code class="literal">{ 0, NULL }</code>.
Typically the strings you use should be semi-human-readable, for GTK+ and GNOME
stripping off the library prefix and converting to StudlyCaps is the recommended
convention.
</p>
<p>
The function returns <span class="symbol">TRUE</span> if a match for the string is found,
and if a match is found the enum value is placed in <em class="parameter"><code>enum_value_retloc</code></em>.
