    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 toa statically allocated rpcent structure. A NULL pointer is returned on EOF or error.  

    FILES

    /etc/rpc
    RPC program number database.
