getrpcbyname

       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
       The getrpcent(), getrpcbyname(), and  getrpcbynumber()  functions  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.

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

       The 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.

       The  getrpcbyname()  and getrpcbynumber() functions 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 structure.  A NULL pointer  is
       returned on EOF or error.
