Converts an exception into Cardinal value to be returned from DLL.
Unit
EBase
Syntax
Code (Delphi)
|
function GetExceptionErrorCode(
const AExceptObject: TObject
): Cardinal;
|
Return value
A Cardinal value to be returned to the caller - possibly via SetLastError.
Remarks
This is a helper function, which can be used to return value as GetLastError or ExitCode for thread/process.
Important!
|
Be sure to cast the returned Cardinal value to Integer when necessary! For example, old Delphi IDEs declare SetLastError/GetLastError using an Integer argument (while modern IDEs declare these function using Cardinal). The same is true when assigning the returned value to Delphi's exit codes - which use Integer as opposed to Cardinal exit codes in Windows.

Examples
Code (Delphi)
|
function Test: Boolean; stdcall;
begin
try
// Your actual payload (work) code should be placed here
Result := True;
except
SetLastError(GetExceptionErrorCode(ExceptObj));
Result := False;
end;
end;
