Variant.getBytestring
string getBytestring()Returns the string value of a #GVariant instance with an array-of-bytes type. The string has no particular encoding.
If the array does not end with a nul terminator character, the empty string is returned. For this reason, you can always trust that a non-null nul-terminated string will be returned by this function.
If the array contains a nul terminator character somewhere other than the last byte then the returned string is the string, up to the first such nul character.
[glib.variant.Variant.getFixedArray] should be used instead if the array contains arbitrary data that could not be nul-terminated or could contain nul bytes.
It is an error to call this function with a value that is not an array of bytes.
The return value remains valid as long as value exists.
