type direction = | In in argument. | Out out argument. | InOut in and out argument.: The direction of a Arg_info.

type transfer = | Nothing transfer nothing from the callee (function or the type instance the property belongs to) to the caller. The callee retains the ownership of the transfer and the caller doesn't need to do anything to free up the resources of this transfer. | Container transfer the container (list, array, hash table) from the callee to the caller. The callee retains the ownership of the individual items in the container and the caller has to free up the container resources (g_list_free()/ g_hash_table_destroy() etc) of this transfer. | Everything transfer everything, eg the container and its contents from the callee to the caller. This is the case when the callee creates a copy of all the data it returns. The caller is responsible for cleaning up the container and item resources of this transfer.

`\|` `Nothing`	transfer nothing from the callee (function or the type instance the property belongs to) to the caller. The callee retains the ownership of the transfer and the caller doesn't need to do anything to free up the resources of this transfer.
`\|` `Container`	transfer the container (list, array, hash table) from the callee to the caller. The callee retains the ownership of the individual items in the container and the caller has to free up the container resources (g_list_free()/ g_hash_table_destroy() etc) of this transfer.
`\|` `Everything`	transfer everything, eg the container and its contents from the callee to the caller. This is the case when the callee creates a copy of all the data it returns. The caller is responsible for cleaning up the container and item resources of this transfer.

`\|` `Invalid`	The argument is not of callback type.
`\|` `Call`	The callback and associated user_data is only used during the call to this function.
`\|` `Async`	The callback and associated user_data is only used until the callback is invoked, and the callback. is invoked always exactly once.
`\|` `Notified`	The callback and and associated user_data is used until the caller is notfied via the destroy_notify.
