HRFunc
Specifies the type of the function passed to func@GLib.HashTable.find, func@GLib.HashTable.foreach_remove, and func@GLib.HashTable.foreach_steal.
The function is called with each key/value pair, together with the @user_data parameter passed to the calling function.
The function should return true if the key/value pair should be selected, meaning it has been found or it should be removed from the struct@GLib.HashTable, depending on the calling function.
return true if the key/value pair should be selected, and false otherwise
