GKeyFile use on Windows

[Richard Gipps <rgipps netspace net au>]

I am looking at using the GKeyFile facility in GLIB for storing settings of 
an application I am writing in Windows.  While I can see how to retrieve 
the setting from a file there does not seem to be a function to write a 
GKeyFile to a disk file.  So does this mean you have to create a GKeyFile 
using g_key_file_new(), add the keys, then use g_key_file_to_data() to 
write the data to a string, then write the string to a file?  Or is the 
GKeyFile written to the registry some how?

Richard.
