    NAME

    getrpcbyname

    LIBRARY

    Lb libc
    
     
    

    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:

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

    The setrpcent ();
    function opens and rewinds the file. If the Fa 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

     

    DIAGNOSTICS

    A NULL pointer is returned on EOF or error.  

    SEE ALSO

    BUGS

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