Method Stdio.File()->set_callbacks()

Method set_callbacks

void set_callbacks(read_callback_t|void read_cb, write_callback_t|void write_cb, close_callback_t|void close_cb, read_oob_callback_t|void read_oob_cb, write_oob_callback_t|void write_oob_cb)

Description

Installs all the specified callbacks at once. Use UNDEFINED to keep the current setting for a callback.

Like set_nonblocking, the callbacks are installed atomically. As opposed to set_nonblocking, this function does not do anything with the stream, and it doesn't even have to be open.
