As I know submitting ECR needs log in as a member at http://www.uefi.org/memberslogin, I am not sure the whole process. If needed, I can help to submit the ECR.
According to EDK2 coding style doc at https://edk2-docs.gitbooks.io/edk-ii-c-coding-standards-specification/content/5_source_files/57_c_programming.html#table-9-parameter-modifiers IN OUT Passed by reference, and the passed-in referenced data is consumed and then modified by the routine. But the code will not consume the pass in referenced data. Personally, I don't think just checking NULL pointer should be marked as 'IN' Thanks, Star -----Original Message----- From: Marvin H?user [mailto:[email protected]] Sent: Tuesday, July 25, 2017 4:58 PM To: [email protected] Cc: Zeng, Star <[email protected]> Subject: RE: [UEFI PI 1.6/EDK2] Missing decorators for EFI_PEI_GET_VARIABLE2. Hey Star, Thanks for your comment! Sorry, I never submited such a report, could you please point me in the right direction? The only way of contact I found on the site of the UEFI Forum were Administration and Press, both don't sound like the right place to post to. Or Is 'Administration' specification administration rather than forum administration? Regarding 'IN': Correct me if I'm wrong, but in contrast to just 'OUT' parameters, which are 'blindly' written to, 'Attributes' must be checked against NULL first before attempting a dereference. Is this not the correct usage of IN? Is IN only used, when the pointer's destination is read? Thanks again!
