NAME
       getrpcent, getrpcbyname, getrpcbynumber - get RPC entry

SYNOPSIS
       #include <netdb.h>

       struct rpcent *getrpcent()

       struct rpcent *getrpcbyname(name)
       char *name;

       struct rpcent *getrpcbynumber(number)
       int number;

       setrpcent (stayopen)
       int stayopen;

       endrpcent ()

DESCRIPTION
       getrpcent(), getrpcbyname(), and getrpcbynumber() each return a pointer to an object with the following structure containing the broken-out
       fields of a line in the rpc program number data base, /etc/rpc.

	      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 zero terminated list of alternate names for the rpc program.
	      r_number		  The rpc program number for this service.

       getrpcent() reads the next line of the file, opening the file if necessary.

       getrpcent() opens and rewinds the file.	If the stayopen flag is non-zero, the net data base will not be closed after each call	to  getrp-
       cent() (either directly, or indirectly through one of the other "getrpc" calls).

       endrpcent closes the file.

       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.

FILES
       /etc/rpc

SEE ALSO
       rpc(5), rpcinfo(8), ypserv(8)

DIAGNOSTICS
       A NULL pointer is returned on EOF or error.

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