.Sh DESCRIPTION
|
|
.Fn getrpcent ,
|
|
.Fn getrpcbyname ,
|
|
and
|
|
.Fn 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,
|
|
.Pa /etc/rpc :
|
|
.Bd -literal -offset indent
|
|
struct rpcent {
|
|
char *r_name; /* name of server for this rpc program */
|
|
char **r_aliases; /* alias list */
|
|
long r_number; /* rpc program number */
|
|
};
|
|
.Ed
|
|
.Pp
|
|
The members of this structure are:
|
|
.Bl -tag -width r_aliases -offset indent
|
|
.It r_name
|
|
The name of the server for this rpc program.
|
|
.It r_aliases
|
|
A zero terminated list of alternate names for the rpc program.
|
|
.It r_number
|
|
The rpc program number for this service.
|
|
.El

|
|
.Fn getrpcent
|
|
reads the next line of the file, opening the file if necessary.
|
|
.Pp
|
|
.Fn setrpcent
|
|
opens and rewinds the file. If the
|
|
.Fa stayopen
|
|
flag is non-zero,
|
|
the net data base will not be closed after each call to
|
|
.Fn getrpcent
|
|
(either directly, or indirectly through one of
|
|
the other
|
|
.Dq getrpc
|
|
calls).
|
|
.Pp
|
|
.Fn endrpcent
|
|
closes the file.
|
|

|
|
.Fn getrpcbyname
|
|
and
|
|
.Fn 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.
