Not quite sure why were getting these errors

/home/runner/work/h3/h3/src/apps/testapps/testGridRing.c:32:35: error: call to undeclared function 'gridRing'; ISO C99 and later do not support implicit function declarations [-Wimplicit-function-declaration]
   32 |         t_assertSuccess(H3_EXPORT(gridRing)(sfHex, 0, k0));
      |    

when the test file has:

#include "h3api.h"

also my first time writing in C so any help is appreciated!

The issue is because the declaration needs to be added to h3api.h.in (which gets processed into h3api.h), otherwise the compiler isn't sure what that function looks like.

Thanks for this contribution! I will take a look in more detail.

If you're comfortable, could you also add this function to fuzzerGridDisk so we get the full fuzzer coverage? (We can also add that in a follow up)

Ah I didn't notice that src/h3lib/include/h3api.h was local and in .gitignore, thanks!

Would prefer if someone could help me do that in a followup, thank you :)
