Carver’s team are in freefall after a six-game losing streak.
The relegation-threatened club is braced for a five-game battle to stay in the Premier League.
And Newcastle will take on Swansea City at St James’s Park tomorrow in desperate need of three points.
The last few weeks of the campaign will be played out amid more protests from disillusioned supporters, some of whom boycotted last weekend’s home defeat to Tottenham Hotspur.
Members of United’s Fans Forum this week wrote an open letter to owner Mike Ashley asking him to make a “statement of intent” after another dismal season.
They demanded to know how Ashley and Newcastle’s hierarchy plan to revive the club’s fortunes.
And they also asked the club to clarify whether Carver was set to be appointed as Newcastle’s head coach on a permanent basis.
Derby County head coach Steve McClaren is the two frontrunners for the post, but Carver remains a candidate.
While Carver has been involved in discussions about the club’s summer transfer strategy and pre-season with managing director Lee Charnley and chief scout Graham Carr, he is adamant he has not been given any assurances about his future.
Carver, however, does have five years left on his assistant manager’s contract.
Asked if he had been told he would be given the post on a full-time basis, Carver said: “Absolutely not. On the gospel, I haven’t been told that.
“We have had discussions about ongoing issues at the club and I have regular meetings with Lee and Graham, at least once a week.
“I have not been given any assurances or been told what my situation is next season.
“What I have got is a five-year deal.”
Newcastle’s squad has been depleted by a series of injuries and suspensions, and Carver says the club’s hierarchy “understands” the impact these have had on results over the past few months.
Asked if the next five games would have a bearing on his future, Carver added: “I don’t know.
“I think people understand the situation I’m in, and know what I’m trying to do.
“Only they (United’s board) know. But every time I get together with them they are positive – whether that’s to keep me going or they have someone else lined up, I don’t know.
“That doesn’t affect me, the future will take care of itself. I’m just concentrating on now.”
Carver does expect a quick decision on the club’s full-time head coach at the end of the season.
Asked if he expected a swift announcement, he said: “Definitely – that would be for everyone’s benefit.
“The fans, myself, everyone could enjoy their summer.
“I think it will be (sorted quickly), because don’t forget the window opens very soon after the season finishes.
“It has to be done and your recruitment has to be done in that period of time.”
