Conditional Compilation Straddling Function Definitions

Tue, 08/10/2010 - 03:47 pm

IP Manual:

Conditionals must be either completely outside or completely inside function definitions; they cannot straddle a function definition.

I would appreciate the ability to have conditional compilation straddle function definitions.

Motivation: I am in the process of debugging a large codebase of interdependent ThreadSafe functions. It would be very handy to be able to remove the ThreadSafe declaration from them all with a #define setting, enabling the Igor debugger.

Example code using wished-for feature:

#define USETHREADSAFE 

#if USETHREADSAFE

ThreadSafe Function myFunc(var, str)

#else

Function myFunc(var, str)

#endif

   Variable var

   String str

   // Function body

End

I'm sure others could come up with more clever uses, too.

There's no harm in leaving a function marked Threadsafe; you can still call it from a non-Threadsafe routine.

As far as conditional compilation straddling function definitions, I can see it being useful, but it would come at a cost: development time that could be better spent elsewhere.
