Optional API for GIO modules to implement.
Should return a list of all the extension points that may be
implemented in this module.
This method will not be called in normal use, however it may be
called when probing existing modules and recording which extension
points that this model is used for. This means we won't have to
load and initialze this module unless its needed.
If this function is not implemented by the module the module will
always be loaded, initialized and then unloaded on application startup
so that it can register its extension points during init.
Note that a module need not actually implement all the extension points
that g_io_module_query returns, since the exact list of extension may
depend on runtime issues. However all extension points actually implemented
must be returned by g_io_module_query() (if defined).
When installing a module that implements g_io_module_query you must
run gio-querymodules in order to build the cache files required for
lazy loading.
Since 2.24
A NULL-terminated array of strings, listing the supported extension points of the module. The array must be suitable for freeing with g_strfreev(). [transfer full]
