test/acl_test.cpp:95:3:
  Type: Unchecked return value (CHECKED_RETURN)

test/acl_test.cpp:95:3: Unchecked call to function
  1. check_return: Calling "acl_set_hal" without checking return value (as is done elsewhere 28 out of 31 times).
src/acl_globals.cpp:182:3: Examples where return value from this function is checked
  2. example_checked: Example 1: "acl_set_hal(board_hal)" has its value checked in "acl_set_hal(board_hal)".
test/acl_globals_test.cpp:697:1: Examples where return value from this function is checked
  3. example_checked: Example 2: "acl_set_hal(acl_test_get_simple_hal())" has its value checked in "acl_set_hal(acl_test_get_simple_hal())".
test/acl_hal_test.cpp:303:3: Examples where return value from this function is checked
  4. example_checked: Example 3: "acl_set_hal(&simple_hal)" has its value checked in "acl_set_hal(&simple_hal)".
test/acl_hal_test.cpp:181:3: Examples where return value from this function is checked
  5. example_checked: Example 4: "acl_set_hal(&simple_hal)" has its value checked in "1 == acl_set_hal(&simple_hal)".
test/acl_hal_test.cpp:232:3: Examples where return value from this function is checked
  6. example_checked: Example 5: "acl_set_hal(&bad_hal)" has its value checked in "0 == acl_set_hal(&bad_hal)".
