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 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.

FILES
       /etc/rpc
	      RPC program number database.
