The explain_iocontrol_vidioc_subscribe_event global variable is used to store information about the VIDIOC_SUBSCRIBE_EVENT I/O control.

Note:

This information is not kept in a single table for all values, like every other set of constants, because (a) some values are ambiguous, and (b) the include files have bugs making it impossible to include all of them in the same compilation unit.
