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¶
Thegetrpcent
(), 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.
