I recently downloaded MISRA C:2012, third edition, first revision, February 2019. The text for Rule 22.9 on page 190 says, "The value of errno shall be set to zero after calling an errno-setting-function" (emphasis mine). But the amplification, rationale, and exception all seem to deal with the testing of errno, not the setting of errno. The rule in Appendix A (on page 203) says, "..shall be tested against zero...", as does the version of the rule in the 2016 addendum. Seems like the text on page 190 probably needs to be fixed.
