2019-08-21libmemif: introduce 'memif_per_thread_' namespaceJakub Grajciar9-113/+1314
APIs in 'memif_per_thread_' namespace are used to split the global database into separate databases, to improve multi-thread use cases. Using 'memif_per_thread_init' client can create separate libmemif databases (libmemif_main_t). Client will reference these databases using memif_per_thread_handle_t. Each database requires unique socket. Created interface will be stored in the same database as the socket passed in connection arguments.

2019-07-02libmemif: version 3.0Jakub Grajciar12-339/+423
Add support for multi-thread connection establishment. - control_fd_update() callback now passes private context associated with updated file descriptor. File descriptor can belong to memif socket, memif connection or timerfd. In case of timerfd the context is NULL. - memif_create_socket() new API. Creates memif socket handle to be passed to memif_create() in memif_conn_args_t. This API allows to pass private context whenever the file descriptor is updated. - memif_delete_socket() new API. Deletes memif socket. Socket must not be in use by any interface. Type: feature Change-Id: I7ca4e4349595d4477195f1c32403d3e3a6eb5361 Signed-off-by: Jakub Grajciar <jgrajcia@cisco.com>
