DOCUMENT:Q152010 12-JUN-2001 [sna] TITLE :LUA RUI/SLI Calls May Return Immediately or with LUA_IN_PROGRESS PRODUCT :Microsoft SNA Server PROD/VER::2.0,2.1,2.11,3.0 OPER/SYS: KEYWORDS:kbnetwork kbprogramming ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft SNA Server for Windows NT, versions 2.0, 2.1, 2.11, 3.0 ------------------------------------------------------------------------------- There is no way for an application program to control whether an SNA Server LUA RUI or SLI call will return synchronously (that is, block the calling thread) or asynchronously. The call may complete immediately (for example if data has already arrived to complete a read request), though in most cases the call will return immediately with the primary return code set to LUA_IN_PROGRESS (0x0030). In this case, the application must use whatever asynchronous completion method it chose to wait for the verb to complete. Asynchronous completion methods are described in Chapter 2 (pages 17 and 18) in the SNA Server LUA Programmer's Guide. SNA Server 3.0 documents this in the LUA Programmer's Guide section of the SNA SDK Documentation applet.
