GETRPCENT(3)	       FreeBSD Library Functions Manual 	  GETRPCENT(3)

NAME
     getrpcent, getrpcbyname, getrpcbynumber, endrpcent, setrpcent -- get RPC
     entry

SYNOPSIS
     #include <rpc/rpc.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 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 pro-
		   gram.

     r_number	   The rpc program number for this service.

     The getrpcent() function reads the next line of the file, opening the
     file if necessary.  The setrpcent() function opens and rewinds the file.
     If the stayopen flag is non-zero, the net data base will not be closed
     after each call to getrpcent() (either directly, or indirectly through
     one of the other getrpcent() function family.

     endrpcent() closes the file.

     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.

FILES
     /etc/rpc

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.
