Why is there no macro
  #define streq(a,b) (strcmp (a, b) == 0)
in <string.h>? Because it can be left to the user.

Nevertheless, sometimes you see
  #define is_empty(list) (size_of (list) == 0)
It could be left to the user, but is included in the API because
the size of the list and the concept of an empty list are
distinct concepts (although related and very close).

For my feeling, there's too little added value in such a macro.

Remember the costs of documenting a function or macro:
  - The user needs more time to read the documentation.
  - The developer needs to code and document it.
