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 data-
       base 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 stati-
       cally allocated rpcent structure.  A NULL pointer is returned on EOF or error.

FILES
       /etc/rpc
	      RPC program number database.
