NAME

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

SYNOPSIS

       #include <netdb.h>

       struct rpcent *getrpcent(void);

       struct rpcent *getrpcbyname(char *name);

       struct rpcent *getrpcbynumber(int number);

       void setrpcent(int stayopen);

       void endrpcent(void);

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.

       setrpcent() opens and rewinds  the  file.   If  the  stayopen  flag  is
       nonzero,  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.

RETURN VALUE

       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.
