#if 0 as a define
- by valerio
I need a way to define a FLAGS_IF macro (or equivalent) such that
FLAGS_IF(expression)
<block_of_code>
FLAGS_ENDIF
when compiling in debug (e.g. with a specific compiler switch) compiles to
if (MyFunction(expression))
{
<block_of_code>
}
whereas in release does not result in any instruction, just as it was like this
#if 0
<block_of_code>
#endif
In my ignorance on the matter of c/c++ preprocessors i can't think of any naive way (since #define FLAGS_IF(x) #if 0 does not even compile) of doing this, can you help?
I need a solution that:
Does not get messed up if */ is present inside <block_of_code>
Is sure to generate 0 instructions in release even inside inline functions at any depth (i guess this excludes if (false){<block_of_code>} right?)
Is standard compliant if possible
Thank you
