If I have a "Hello World" function (just prints that) and a similar "Goodbye World" function... is there a way (maybe a compiler option?) that I can get them to be executed directly as the absolute first and last things run in every function call.
So for example, the following code:
should print out:
I assume from this model, that a simple find&replace would work, even using something like grep/sed to add a call to hello() as the first call, and a goodbye() as the last thing before any return/function-exit... but is this doable without manually (including a sed script as "manual") modifying the code? IE, is there a pre-call/post-call function wrapper?...
You can actually use a sed script to replace lines beginning with "{" and "}" with preprocessor directives:
Now the sed scripts:
Compile and make sure it works. Once it does, you can change your macros so that FBEGIN and FEND call a function too, like something that logs to a file:
