RUI and SLI Definitions

  • Article

The definitions of the RUI and SLI functions are as follows:

void WINAPI RUI(struct LUA_VERB_RECORD FAR * verb);  
void WINAPI SLI(struct LUA_VERB_RECORD FAR * verb);  
int WINAPI WinRUI(HWND handle, struct LUA_VERB_RECORD FAR * verb);  
int WINAPI WinSLI(HWND handle, struct LUA_VERB_RECORD FAR * verb);

The WINLUA.H header file supplied with your Host Integration Server SDK includes prototypes of these functions.

The only parameter passed to the RUI or SLI function is the address of a verb control block (VCB). The VCB is a structure made up of variables that:

  • Identify the logical unit application (LUA) verb to be executed.

  • Supply information used by the verb.

  • Contain information returned by the verb when execution is complete.

    The parameters passed to the WinRUIor WinSLI function are a window handle and the address of a VCB. The window handle is used for message notification when the issued verb has completed.

    The VCB structure is declared in the WINLUA.H header file. For general VCB information, see LUA VCB Format. For verb-specific VCB information, see the reference documentation for each verb.
