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:

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.
