Struct _IO_cookie_io_functions_t

#[repr(C)]pub struct _IO_cookie_io_functions_t {
    pub read: cookie_read_function_t,
    pub write: cookie_write_function_t,
    pub seek: cookie_seek_function_t,

}

Expand description

The structure with the cookie function pointers. The tag name of this struct is _IO_cookie_io_functions_t to preserve historic C++ mangled names for functions taking cookie_io_functions_t arguments. That name should not be used in new code.

Fields§

§read: cookie_read_function_t

Read bytes.

§write: cookie_write_function_t

Write bytes.

§seek: cookie_seek_function_t

Seek/tell file position.

§close: cookie_close_function_t

Close file.
