+    Returns the array of bit converted to an int. The conversion is based on \a endianness.
+    Converts up to the first 32 bits of the array to \c quint32 and returns it,
+    obeying \a endianness. If \a ok is not a null pointer, and the array has more
+    than 32 bits, \a ok is set to false and this function returns zero; otherwise,
+    it's set to true.
