GETRPCENT(3)               Linux Programmer's Manual              GETRPCENT(3)

       getrpcent, getrpcbyname, getrpcbynumber, setrpcent, endrpcent - get RPC entry

       #include <netdb.h>

       struct rpcent *getrpcent(void);

       struct rpcent *getrpcbyname(char *name);

       struct rpcent *getrpcbynumber(int number);

       void setrpcent(int stayopen);

       void endrpcent(void);

       getrpcent(),  getrpcbyname(),  and  getrpcbynumber()  each  return  a pointer to an
       object with the following structure containing the broken-out fields of an entry in
       the RPC program number data base.

           struct rpcent {
               char  *r_name;     /* name of server for this RPC program */
               char **r_aliases;  /* alias list */
               long   r_number;   /* RPC program number */

       The members of this structure are:

           r_name      The name of the server for this RPC program.

           r_aliases   A NULL-terminated list of alternate names for the RPC program.

           r_number    The RPC program number for this service.

       getrpcent()  reads the next entry from the database.  A connection is opened to the
       database if necessary.

       setrpcent() function opens a connection to the database, and sets the next entry to
       the first entry.  If stayopen is non-zero, then the connection to the database will
       not be closed between calls to one of the getrpc*() functions.

       The endrpcent() function closes the connection to the database.

       getrpcbyname() and getrpcbynumber() sequentially search from the beginning  of  the
       file until a matching RPC program name or program number is found, or until end-of-
       file is encountered.

       On success, getrpcent(), getrpcbyname(), and getrpcbynumber() return a pointer to a
       statically allocated rpcent structure.  A NULL pointer is returned on EOF or error.

              RPC program number database.

       Not in POSIX.1-2001.  Present on the BSDs, Solaris, and many other systems.

       All information is contained in a static area so it must be copied if it is  to  be
