getrpcbyname

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 an entry in the RPC program number data base.

 
 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 NULL-terminated list of alternate names for the RPC program.

r_number

The RPC program number for this service.

getrpcent() reads the next entry from the database. A connection is opened to the database if necessary.

setrpcent() function opens a connection to the database, and sets the next entry to the first entry. If stayopen is non-zero, then the connection to the database will not be closed between calls to one of the getrpc*() functions.

The endrpcent() function closes the connection to the database.

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

On success, getrpcent(), getrpcbyname(), and getrpcbynumber() return a pointer to a statically allocated rpcent structure. A NULL pointer is returned on EOF or error.

FILES

/etc/rpc

RPC program number database.

CONFORMING TO

Not in POSIX.1-2001. Present on the BSDs, Solaris, and many other systems.

BUGS

All information is contained in a static area so it must be copied if it is to be saved.
