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
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 database, /etc/rpc:
struct rpcent {
char *r_name; /* name of server for this rpc program */
char **r_aliases; /* alias list */
int 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.
setrpcent()
opens and rewinds the file. If the stayopen flag is
non-zero, the net database 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.
FILES
/etc/rpc
DIAGNOSTICS
A NULL pointer is returned on
EOF or error.
