Function Documentation

int main	(	int	argc,
		char *	argv[]
	)

Main entry point.

Returns:

Zero on success, non-zero on error.

Variable Documentation

usbvirt_device_t hid_dev [static]

Initial value:

 {
        .ops = &hid_ops,
        .descriptors = &descriptors,
        .name = "HID",
        .device_data = &vuhid_data
}

Keyboard device.

Rest of the items will be initialized later.

Definition at line 145 of file main.c.

usbvirt_device_ops_t hid_ops [static]

Initial value:

 {
        .control = endpoint_zero_handlers,
}

Keyboard callbacks.

We abuse the fact that static variables are zero-filled.

Definition at line 87 of file main.c.
