Hallo,
CALL_EXTERNAL uses the C calling convention and wants
parameters to be passed in the argc/argv syntax. I have
a Win32-DLL written in Delphi 6 that exports the
following function:
Function GetFloat ( VAR URL: ShortString;
VAR dim: LongInt;
VAR x: AbscissaType
): LongInt;
stdcall;
where the type "ShortString" is a fixed length (Pascal)
string of 255 characters, "LongInt" a signed 32 bit
integer and "Abscissa Type" a fixed length array of 32 bit
floating points (Delphi type "Single").
How must I convert this code to export the function in
argc/argv syntax, so that CALL_EXTERNAL can understand
the input? Anybody a solution or a piece of sample code
in Delphi?
Regards and thanks,
Ralph.
