Parameters

str

Type: const gunichar*

A UCS-4 encoded string.

error

Type: GError **

The argument will left initialized to NULL by the function if there are no errors.
In case of error, the argument will be set to a newly allocated GError; the caller will take ownership of the data, and be responsible for freeing it.
