GETRPCENT(3)          DragonFly Library Functions Manual          GETRPCENT(3)

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

LIBRARY
     Standard C Library (libc, -lc)

SYNOPSIS
     #include <rpc/rpc.h>

     struct rpcent *
     getrpcent(void);

     struct rpcent *
     getrpcbyname(const 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
                      program.

           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
     "getrpc" calls).

     The endrpcent() function closes the file.

     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 VALUES
     A NULL pointer is returned on EOF or error.

FILES
     /etc/rpc

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