Macro for concatenating two strings in C

I have a function that looks something like this:

bool module_foo_process(void* bar) { return doMagic(bar); }

Now, I’d like to generate it with a macro. For instance, the macro for the above function would look like this:

MY_AMAZING_MACRO(foo)

This allows me to write something like:

MY_AMAZING_MACRO(awesome)

and get this:

bool module_awesome_process(void* bar) { return doMagic(bar); }

Any ideas on how this can be accomplished in C?

Answer 1

#define MY_AMAZING_MACRO(name) \
  bool module_##name##_process(void* bar) { return doMagic(bar); }
