| Subject: | Using a C++ dll in delphi |

The C++ dll declaration is
LPSTR ConvertName(char* firstname, char* middlename, char* lastname)
I'm trying to call it as such (pseudo code)
function MyConvertNameWrapper( aFirst, aMiddle, aLast: PChar): PChar;
begin
Result := nil;
LoadLibrary( DLL );
try
PROC := GetProcAddRess( DLLHandle, ProcName );
if Assigned( PROC ) then
StrLCopy( Result, PROC( PChar(First),PChar(Middle),PChar(Last) ) );
finally
FreeLibrary( DLLHandle );
end;
end;
Is the StrLCopy the proper way to do this? Anything else I try either
blows up calling the PROC or corrupts my stack and blows up when I leave
my wrapper method.
