NAME

getrpcent, getrpcbyname, getrpcbynumber, setrpcent, endrpcent - get RPC entry

SYNOPSIS

#include <netdb.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 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:

getrpcent() reads the next line of the file, opening the file if necessary.

setrpcent() opens and rewinds the file. If the stayopen flag is nonzero, 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.

RETURN VALUE

A NULL pointer is returned on EOF or error.

FILES

/etc/rpc
