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


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


     #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);


     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
         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.


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