Calling a function with pcall in coroutine.wrap

Help and Feedback Scripting Support
#1

I can’t seem to find the answer to this. The question is simple, how do I call a function with pcall while also using coroutine.wrap?

#2 
local function coolFunction()
   local success, errormsg = pcall(function()

   end)
   if success then
      return "good function"
   end
end

local betterfunction = coroutine.wrap(coolFunction)

print(betterfunction())

or if you mean other thing:

local function yourFunction()
   print("haha very funni")
   return "yes"
end

local success, returnedOrError = pcall(function()
   local NewFunction = coroutine.wrap(yourFunction)

  return NewFunction()
end)
if returnedOrError == "yes" then
  print("It works")
end
