How to check if net messages exist

[eth0s]

local function checkForNetworkMessage()
    net.Start("RandomMessage")
end

local function catch()
    print("Didn't Find")
end

local didSucceed = xpcall(checkForNetworkMessage, catch)

if didSucceed then
  print("Succeeded")
end

Heres some free codes to check if net messages exist or not.
A friend asked me to make this for him and im gonna release it here so other people can use it.

util.NetworkStringToID( string ) != 0

That works the same way. I'm sure your function works too though.
