*$dllcall(filename, alias, procname, data)*

$dllcall is multi-threaded so it will not halt the script and will call the specified alias once the dll responds.

*Parameters*

filename - DLL file to call.
alias - Alias to execute when the dll responds.
procname - Procname to call.
data - Data to send to the dll.
