Reentrant?

Cpt. Vince

I rarely ask questions on this forum, but since I couldn't [easily] find it in the help-files, or on-line, I'm asking you guys.

I usually (like never) don't use the 'reentrant' pragma, but I think I may have to do that with a particular routine.

BUT I can't find the key-word that declares a function as reentrant. Am I missing something? Is there one for Keil's IDE tools? If so, what is its form? Can I get a link to the 'official' use of it?

Thanks in advance, and I need it asap because I need to pass this class and I don't want to really learn how to do this 'embedded' stuff anyway but the teacher keeps hounding me.

    Ho Jack,

    You must be supremely proud that Vince is using your name for target practicing (as he demonstrated here:http://www.keil.com/forum/docs/thread14479.asp).

    :-)

    A quick quote:

    locked_on_1 = Get_Evil_Bad_Guy_Image( IR_CAMERA_1, &sardine_image.frame.current  );

 locked_on_2 = Get_Evil_Bad_Guy_Image( IR_CAMERA_2, &sprat_image.frame.current    );

 locked_on_3 = Get_Evil_Bad_Guy_Image( IR_CAMERA_3, &smoked_image.frame.current   );

 locked_on_4 = Get_Evil_Bad_Guy_Image( IR_CAMERA_3, &jack_image.frame.current     );

 lock_complete = ( (    ( locked_on_1 != FALSE )
                     && ( locked_on_2 != FALSE )
                     && ( locked_on_3 != FALSE )
                     && ( locked_on_4 != FALSE )

                   ) != FALSE
                 )
                     ?     // ternary = ( cond==TRUE )? TRUE : FALSE ;

                    TRUE   // TRUE == !FALSE, so TRUE goes here

                     :

                    FALSE
                 ; // end ternary, end assignment

 // if true, then bad things happen to bad guys...
 if( lock_complete != FALSE )
 {
    Enable( BAD_THINGS );
    ...
 }
 else
 {
    Disable( BAD_THINGS ); // just in case
 }
