Important Notice

The pages on this site contain documentation for very old MS-DOS software, purely for historical purposes. If you're looking for up-to-date documentation, particularly for programming, you should not rely on the information found here, as it will be woefully out of date.

     The VARARG attribute allows you to pass a variable number of
     arguments to a procedure. The VARARG parameter receives a near
     pointer to an array of WORD elements (DWORD if a far address is
     passed). You can apply the VARARG attribute only to the last
     parameter in a procedure definition. You can only use VARARG in
     procedures when the C, SYSCALL, or STDCALL language types are in
     effect.
