GETRPCENT(3)                  Linux Programmer's Manual                  GETRPCENT(3)

NAME         top

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

SYNOPSIS         top

       #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         top

       getrpcent(), getrpcbyname(), and getrpcbynumber() 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.

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

       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.

       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         top

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

FILES         top

       /etc/rpc
              RPC program number database.

CONFORMING TO         top

       Not in POSIX.1-2001.  Present on the BSDs, Solaris, and many other systems.

BUGS         top

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