Research direction
Start with the zesDriverEventListen[Ex] specification section linked in the issue and review its current timeout and return-code wording. Determine whether an explicit timeout result and behavior before the requested time expires are intended, then document the agreed API semantics; done means the specification is unambiguous and the change has maintainer agreement.
Written by the indexing model from the issue text.
Description
I suggest adding an explicit timeout return code for zesDriverEventListen[Ex] calls. Right now, the user has to infer a timeout occurred when ze_result_t == ZE_SUCCESS and pNumDeviceEvents = 0. The specification isn't 100% clear that a timeout will result in the pNumDeviceEvents being cleared. An explicit error code leaves no doubt. The spec is also ambitious in stating that the timeout will only occur once the time expires. It seems like an -EINTR or similar type error could cause a timeout to occur before the time expires. Perhaps the spec should allow for a timeout to occur before the time expires?
