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¶

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:

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.

FILES¶

/etc/rpc

 

AVAILABILITY¶

These functions are part of libtirpc.
