       guestfs-erlang — як користуватися libguestfs з програми мовою Erlang

КОРОТКИЙ ОПИС

        {ok, G} = guestfs:create(),
        ok = guestfs:add_drive_opts(G, Disk,
                                    [{format, "raw"}, {readonly, true}]),
        ok = guestfs:launch(G),
        [Device] = guestfs:list_devices(G),
        ok = guestfs:close(G).

ОПИС

       This manual page documents how to call libguestfs from the Erlang programming language.
       This page just documents the differences from the C API and gives some examples.  If you
       are not familiar with using libguestfs, you also need to read guestfs(3).

   OPENING AND CLOSING THE HANDLE
       The Erlang bindings are implemented using an external program called "erl-guestfs".  This
       program must be on the current PATH, or else you should specify the full path to the
       program:

        {ok, G} = guestfs:create().

        {ok, G} = guestfs:create("/шлях/до/erl-guestfs").

       "G" is the libguestfs handle which you should pass to other functions.

       Закриття обробника:

        ok = guestfs:close(G).

   ФУНКЦІЇ І ДОДАТКОВІ ПАРАМЕТРИ
       For functions that take optional arguments, the first arguments are the non-optional ones.
       The last argument is a list of tuples supplying the remaining optional arguments.

        ok = guestfs:add_drive_opts(G, Disk,
                                    [{format, "raw"}, {readonly, true}]).

       If the last argument would be an empty list, you can also omit it:

        ok = guestfs:add_drive_opts(G, Disk).

   ЗНАЧЕННЯ, ЩО ПОВЕРТАЮТЬСЯ, І ПОМИЛКИ
       On success, most functions return a "Result" term (which could be a list, string, tuple
       etc.).  If there is nothing for the function to return, then the atom "ok" is returned.

       On error, you would see one of the following tuples:

       "{помилка, повідомлення, номер_помилки}"
           Позначає звичайну помилку у функції.

           "Msg" is the error message (string) and "Errno" is the Unix error (integer).

           "Errno" може бути нульовим. Див. "guestfs_last_errno" in guestfs(3).

       "{unknown, Функція}"
           This indicates that the function you called is not known.  Generally this means you
           are mixing "erl-guestfs" from another version of libguestfs, which you should not do.

           "Функція" — назва невідомої функції.

       "{unknownarg, Аргумент}"
           This indicates that you called a function with optional arguments, with an unknown
           argument name.

           "Аргумент" — назва невідомого аргументу.
