I still find it highly confusing. Maybe:
RETURN VALUES
If resolvedname is NULL, it will be allocated and the returned pointer
can be deallocated using free(3). The realpath() function returns
resolvedname on success.
If an error occurs, realpath() returns NULL.
In the error case, if resolvedname was not NULL, it will contain the
pathname which caused the problem.
