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

Returns the value resulting from a call to a [[Scripting DLL|DLL]] designed to work with AdiIRC.

$dllcall is multi-threaded so it will not halt the script and will call the specified alias once the [[Scripting DLL|DLL]] responds.

*Parameters*

filename - [[Scripting DLL|DLL]] file to call.
alias - Alias to execute when the [[Scripting DLL|DLL]] responds.
[[procname]] - Procname to call.
data - Data to send to the [[Scripting DLL|DLL]].
