Function mysqlclient_sys::mysql_client_register_plugin

pub unsafe extern fn mysql_client_register_plugin(mysql: *mut st_mysql,
                                                  plugin: *mut st_mysql_client_plugin)
                                                  -> *mut st_mysql_client_plugin

adds a plugin structure to the list of loaded plugins

This is useful if an application has the necessary functionality (for example, a special load data handler) statically linked into the application binary. It can use this function to register the plugin directly, avoiding the need to factor it out into a shared object.

@param mysql MYSQL structure. It is only used for error reporting @param plugin an st_mysql_client_plugin structure to register

@retval a pointer to the plugin, or NULL in case of a failure
