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 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

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.
