[PATCH 3/4] remote: Use g_new0 to allocate 'remote_string' in event RPC handlers

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Few events emit optional strings. We need to allocate the container for
it first. Note that remote_nonnull_string is used as the type as the
internal part of the string is nonnull if the container is present.
