getrpcent(3) BSD Library Functions Manual getrpcent(3)
NAME
getrpcent, getrpcbyname, getrpcbynumber, endrpcent, setrpcent -- get RPC
entry
LIBRARY
Standard C Library (libc, -lc)
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 pro-
gram number is found, or until end-of-file is encountered.
FILES
/etc/rpc
DIAGNOSTICS
A NULL pointer is returned on EOF or error.

BUGS
The data space used by these functions is thread-specific; if future use
requires the data, it should be copied before any subsequent calls to
these functions overwrite it.
