GETRPCENT(3)                                                                         GETRPCENT(3)



NAME
       getrpcent, getrpcbyname, getrpcbynumber - get RPC entry

SYNOPSIS
       #include 

       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 num-
       ber 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.

       setrpcent() 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).

       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

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.
