Macro Definition Documentation #define RTE_TAILQ_CAST(tailq_entry, struct_name) (struct struct_name *)&(tailq_entry)->tailq_head Return the first tailq entry cast to the right struct. Definition at line 56 of file rte_tailq.h. #define RTE_TAILQ_LOOKUP(name, struct_name) Value:.PP __extension__ ({ \ struct rte_tailq_head *head = rte_eal_tailq_lookup(name); \ head == NULL ? NULL : RTE_TAILQ_CAST(head, struct_name); \ }) Utility macro to make looking up a tailqueue for a particular struct eas- ier. Parameters name The name of tailq struct_name The name of the list type we are using. (Generally this is the same as the first parameter passed to TAILQ_HEAD macro) Returns The return value from rte_eal_tailq_lookup, typecast to the appropriate structure pointer type. NULL on error. Definition at line 74 of file rte_tailq.h. Function Documentation RTE_TAILQ_HEAD (rte_tailq_entry_head, rte_tailq_entry) dummy void rte_dump_tailq (FILE * f) Dump tail queues to a file. Parameters f A pointer to a file for output struct rte_tailq_head * rte_eal_tailq_lookup (const char * name) Lookup for a tail queue. Get a pointer to a tail queue header of a tail queue identified by the name given as an argument. Note: this function is not multi-thread safe, and should only be called from a single thread at a time Parameters name The name of the queue. Returns A pointer to the tail queue head structure. int rte_eal_tailq_register (struct rte_tailq_elem * t) Register a tail queue. Register a tail queue from shared memory. This function is mainly used by EAL_REGISTER_TAILQ macro which is used to register tailq from the different dpdk libraries. Since this macro is a constructor, the function has no ac- cess to dpdk shared memory, so the registered tailq can not be used before call to rte_eal_init() which calls rte_eal_tailqs_init(). Parameters t The tailq element which contains the name of the tailq you want to create (/retrieve when in secondary process). Returns 0 on success or -1 in case of an error.
