Xhajt03: Since which OS/2 version is this API function available - anybody?

Martini: According to the Google Gemini AI, it was available since OS/2 Warp 4.0, but IBM accidentally omitted its definition from the developer SDK imports library (OS2386.LIB). It was officially patched and restored to the toolkit via Warp 4 Fixpak 5.
