/**
* g_io_module_query:

*
* 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 initialize 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 2.56, this function should be named `g_io_<modulename>_query`, where
* `modulename` is the plugins filename with the `lib` or `libgio` prefix and
* everything after the first dot removed, and with `-` replaced with `_`
* throughout. For example, `libgiognutls-helper.so` becomes `gnutls_helper`.
* Using the new symbol names avoids name clashes when building modules
* statically. The old symbol names continue to be supported, but cannot be used
* for static builds.
*
* Returns: (transfer full): A %NULL-terminated array of strings,
* listing the supported extension points of the module. The array
* must be suitable for freeing with g_strfreev().

* Since: 2.24
