Parameters

buf

Type: guint8*

A buffer to use, which must be large enough for the request.

The data is owned by the caller of the method.

Some FuUdevDeviceIoctlFlags, e.g. FU_UDEV_DEVICE_IOCTL_FLAG_RETRY.

error

Type: GError **

The return location for a recoverable error.

The argument can be NULL.

If the return location is not NULL, then you must initialize it to a NULL GError*.

The argument will be left initialized to NULL by the method if there are no errors.

In case of error, the argument will be set to a newly allocated GError; the caller will take ownership of the data, and be responsible for freeing it.

TRUE for success.
