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 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 nonzero, then the con-
       nection 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 begin-
       ning 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 structure.  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 sys-
       tems.

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