getrpcent, getrpcbyname, getrpcbynumber - get RPC entry
Návod, kniha: Library Functions Manual
#include <netdb.h>
struct rpcent *getrpcent()
struct rpcent *getrpcbyname(name)
char *name;
struct rpcent *getrpcbynumber(number)
int number;
setrpcent (stayopen)
int stayopen;
endrpcent ()
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.
getrpcent() 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).
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.

rpcinfo(8),

A
NULL pointer is returned on
EOF or error.
All information is contained in a static area so it must be copied if it is to
be saved.
