This page just documents the differences from the C \s-1API\s0 and gives some examples. If you are not familiar with using libguestfs, you also need to read \fIguestfs\fR\|(3). .SS "СТИЛІ ПРОГРАМУВАННЯ" .IX Subsection "СТИЛІ ПРОГРАМУВАННЯ" There are two different programming styles supported by the OCaml bindings. You can use a module style, with each C function mapped to an OCaml function: .PP .Vb 1 \& int guestfs_set_verbose (guestfs_h *g, int flag); .Ve .PP перетворюється на: .PP .Vb 1 \& val Guestfs.set_verbose : Guestfs.t \-> bool \-> unit .Ve .PP Alternately you can use an object-oriented style, calling methods on the class \f(CW\*(C`Guestfs.guestfs\*(C'\fR: .PP .Vb 1 \& method set_verbose : bool \-> unit .Ve .PP The object-oriented style is usually briefer, and the minor performance penalty isn't noticeable in the general overhead of performing libguestfs functions. .SS "\s-1CLOSING THE HANDLE\s0" .IX Subsection "CLOSING THE HANDLE" The handle is closed when it is reaped by the garbage collector. Because libguestfs handles include a lot of state, it is also possible to close (and hence free) them explicitly by calling \f(CW\*(C`Guestfs.close\*(C'\fR or the \f(CW\*(C`#close\*(C'\fR method. .SS "ВИНЯТКИ" .IX Subsection "ВИНЯТКИ" Errors from libguestfs functions are mapped into the \f(CW\*(C`Guestfs.Error\*(C'\fR exception. This has a single parameter which is the error message (a string). .PP Calling any function/method on a closed handle raises \&\f(CW\*(C`Guestfs.Handle_closed\*(C'\fR. The single parameter is the name of the function that you called. .SH "ПРИКЛАД. СТВОРЕННЯ ОБРАЗУ ДИСКА" .IX Header "ПРИКЛАД. СТВОРЕННЯ ОБРАЗУ ДИСКА" \&\f(CW@CREATE_DISK\fR@ .SH "ПРИКЛАД.
