getprotoent(3)             Library Functions Manual             getprotoent(3)

JMENO
       getprotoent, getprotobyname, getprotobynumber, setprotoent, endprotoent
       - funkce pro praci s databazi protokolu

KNIHOVNA
       Standardni knihovna C (libc, -lc)

POUZITI
       #include <netdb.h>

       struct protoent *getprotoent(void);

       struct protoent *getprotobyname(const char *name);
       struct protoent *getprotobynumber(int proto);

       void setprotoent(int stayopen);
       void endprotoent(void);

POPIS
       Funkce getprotoent() precte dalsi zaznam z databaze protokolu (viz
       protocols(5)) a vrati strukturu protoent, ktera obsahuje jednotliva
       pole. Pripojeni k databazi je otevreno, je-li potreba.

       Funkce getprotobyname() vraci strukturu protoent ze databaze pro radek,
       ktery vyhovuje jmenu name. Pripojeni k databazi je otevreno, je-li
       potreba.

       Funkce getprotobynumber() vraci strukturu protoent z databaze pro
       radek, ktery vyhovuje protokolovemu cislu number.  Pripojeni k databazi
       je otevreno, je-li potreba.

       The setprotoent()  function opens a connection to the database, and
       sets the next entry to the first entry.  If stayopen is nonzero, then
       the connection to the database will not be closed between calls to one
       of the getproto*()  functions.

       Funkce endprotoent() uzavira spojeni s databazi.

       Struktura protoent je definovana v <netdb.h> nasledovne:

           struct protoent {
               char  *p_name;       /* official protocol name */
               char **p_aliases;    /* alias list */
               int    p_proto;      /* protocol number */
           }

       Prvky struktury protoent jsou:

       p_name Oficialni jmeno protokolu.

       p_aliases
              Nulovym ukazatelem ukonceny seznam prezdivek protokolu.

       p_proto
              Cislo protokolu.

NAVRATOVE HODNOTY
       Funkce getprotoent(), getprotobyname() a getprotobynumber() vraci
       strukturu protoent structure, nebo NULL, jestlize doslo k chybe nebo
       byl dosazen konec souboru.

       In the above table, protoent in race:protoent signifies that if any of
       the functions setprotoent(), getprotoent(), or endprotoent()  are used
       in parallel in different threads of a program, then data races could
       occur.
