NAME

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

SYNOPSIS

     #include <rpc/rpc.h>

     struct rpcent *
     getrpcent(void);

     struct rpcent *
     getrpcbyname(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 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.

     The getrpcent() function reads the next line of the file, opening the file if necessary.

     The setrpcent() function 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).

     The endrpcent() function closes the file.

     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.
