Typedef Documentation

◆ addrinfo_lists_t

typedef struct addrinfo_lists addrinfo_lists_t

A struct with lists of resolved addresses. Used when writing name resolutions blocks (NRB)

◆ wtap_dump_params

typedef struct wtap_dump_params wtap_dump_params

Parameters for various wtap_dump_* functions, specifying per-file information. The structure itself is no longer used after returning from wtap_dump_*, but its pointer fields must remain valid until wtap_dump_close is called.

Note: The shb_hdr and idb_inf arguments will be used until wtap_dump_close() is called, but will not be free'd by the dumper. If you created them, you must free them yourself after wtap_dump_close(). dsbs_initial will be unreferenced by wtap_dump_close(), so to reuse them for another dump file, call wtap_block_array_ref() before closing. dsbs_growing typically refers to another wth->dsbs. nrbs_growing typically refers to another wth->nrbs.

See also: wtap_dump_params_init, wtap_dump_params_cleanup.

◆ wtap_new_ipv4_callback_t

typedef void(* wtap_new_ipv4_callback_t) (const unsigned addr, const char *name, const bool static_entry)

◆ wtap_new_secrets_callback_t

typedef void(* wtap_new_secrets_callback_t) (uint32_t secrets_type, const void *secrets, unsigned size)
