Description [src]

NOTE: In version 2.0.0 the bufsz parameter was added — which isn’t required to perform the
ioctl, but is required to accurately track and emulate the device buffer.
Available since: 2.0.0
Parameters
request-
Type:

FuUdevDeviceIoctlFlagsSome
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 aNULLGError*.The argument will be left initialized to NULLby 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.
