NAME

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

SYNOPSIS

       #include <netdb.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 an entry in the RPC program number data base.

           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 NULL-terminated list of alternate names for the RPC program.

       r_number
              The RPC program number for this service.

       The getrpcent() function reads the next entry from the database.  A connection is opened to the  database
       if necessary.

       The  setrpcent() function opens a connection to the database, and sets the next entry to the first entry.
       If stayopen is nonzero, then the connection to the database will not be closed between calls  to  one  of
       the getrpc*() functions.

       The endrpcent() function closes the connection to the database.

       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 VALUE

       On success, getrpcent(), getrpcbyname(), and getrpcbynumber() return a pointer to a statically  allocated
       rpcent structure.  NULL is returned on EOF or error.

FILES

       /etc/rpc
              RPC program number database.
