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



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

SYNOPSIS
       #include <netdb.h>

       struct rpcent *getrpcent(void);

       struct rpcent *getrpcbyname(char *name);

       struct rpcent *getrpcbynumber(int number);

       void setrpcent(int stayopen);

       void endrpcent(void);

DESCRIPTION
       getrpcent(),  getrpcbyname(),  and  getrpcbynumber() each return a pointer to an object with the following structure con-
       taining 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
       nonzero, 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.

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

FILES
       /etc/rpc
              RPC program number database.

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

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