GETRPCENT(3) Library Functions Manual GETRPCENT(3)

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

Standard C Library (libc, -lc)

#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);

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

The () 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 () function closes the file.

The () and () 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.

/etc/rpc
 

A NULL pointer is returned on EOF or error.

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.
