I'm looking at how to use the esl_recv_event function in esl.c and the docs are missing some details. Could someone tell me: 1. Do I have to lock a mutex before accessing this function (since it dequeues an event) 2. The third parameter is a ptr to a ptr to a struct. So, do I have to allocate a struct before calling (to get the data)? Or will the lib allocate the struct and I have to free it? Comments from esl.c: /*! \brief Poll the handle's socket until an event is received or a connection error occurs \param handle Handle to poll \param check_q If set to 1, will check the handle queue (handle->race_event) and return the last event from it \param[out] save_event If this is not NULL, will return the event received */ ESL_DECLARE(esl_status_t) esl_recv_event(esl_handle_t *handle, int check_q, esl_event_t **save_event); /*!
