Field Documentation

void(* pj_ioqueue_callback::on_read_complete)(pj_ioqueue_key_t *key, pj_ioqueue_op_key_t *op_key, pj_ssize_t bytes_read)

This callback is called when pj_ioqueue_recv or pj_ioqueue_recvfrom completes.

Parameters:

	key	The key.
	op_key	Operation key.
	bytes_read	>= 0 to indicate the amount of data read, otherwise negative value containing the error code. To obtain the pj_status_t error code, use (pj_status_t code = -bytes_read).
