[MLton-devel] RE: release of MLton with _export

[Mike Thomas]

Hi Stephen.

Thanks for letting me know - it seems much better.

A problem occurs with the ffi export example.  However see below...

(I'm in the middle of a pressing problem this morning and SML is looking
like double Dutch to me I'm sorry!)

Cheers

Mike Thomas.

| Hi Mike.  I wanted to let you know about our latest experimental
| release of MLton, 20030625, available at
| http://www.mlton.org/experimental/.  This release includes our latest
| facility for calling SML from C.  Now in SML you can say
|
| _export "foo": real * char -> int;
|
| to export a function "foo" for calling from C.  See the user guide for
| details.
|
| Hopefully this simplifies the FFI stuff enough to not be a hinderance
| to your OpenGL interface.
