GetLuaReturnCode Mapping Problems and Possible Access Violation

 Last reviewed: April 14, 1997
Article ID: Q163561
The information in this article applies to:
  • Microsoft SNA Server for Windows NT, versions 2.1, 2.11, 2.11 Service Pack 1 (SP1), and 3.0

SYMPTOMS

The following problems occur when calling GetLuaReturnCode() from an RUI or SLI application:

- The following return codes are not mapped properly: 

   LUA_RECEIVED_UNBIND 0x55
   LUA_DATA_INCOMPLETE 0x60
   LUA_LU_INOPERATIVE 0xFF

   LUA_RECEIVER_IN_TRANSMIT_MODE  0x081B0000
   LUA_SSCP_LU_SESSION_NOT_ACTIVE 0x08570000

   LUA_RESPONSE_ALREADY_SENT  0x10050122

  Also, GetLuaReturnCode reports these unmapped return codes in Intel
  byte-reversed format.  For example, a sense code of 0x081B0000 may be
  returned as 0x00001B08.
- If GetLuaReturnCode() receives a primary_rc or the secondary_rc that it 
  doesn't expect, this may lead to an access violation in LUASTR32.DLL.

CAUSE

These problems are caused by deficiencies in the GetLuaReturnCode() function.

RESOLUTION

An update to SNA Server 2.11 Service Pack 1 and 3.0 is available to correct these problems. The updated modules are Luastr32.dll, Winrui32.dll and Winsli32.dll.

STATUS

Microsoft has confirmed this to be a problem in SNA Server versions 2.1, 2.11, 2.11 Service Pack 1 (SP1), and 3.0. This problem was corrected in the latest Microsoft SNA Server 2.11 and 3.0 U.S. Service Packs.
