Re: Need clarification on compilation errors in PG 16.2

Hi,

I found out that for using memset() library is not referred from
"/Library/Developer/CommandLineTools/SDKs/MacOSX14.4.sdk/usr/include/string.h"
, it referred from
"/Library/Developer/CommandLineTools/SDKs/MacOSX14.4.sdk/usr/include/secure/_string.h",
in that file didn't defined the memset_s() macro.

Thanks and regards
Pradeep
