[tor-commits] [tor/maint-0.2.1] Automated conversion of memcmp to tor_memcmp/tor_mem[n]eq
commit db7b2a33eef9c8d432442b072f9c8868a068bb91
Author: Nick Mathewson <nickm@xxxxxxxxxxxxxx>

Automated conversion of memcmp to tor_memcmp/tor_mem[n]eq
This commit is _exactly_ the result of
perl -i -pe 's/\bmemcmp\(/tor_memcmp\(/g' src/*/*.[ch]
perl -i -pe 's/\!\s*tor_memcmp\(/tor_memeq\(/g' src/*/*.[ch]
perl -i -pe 's/0\s*==\s*tor_memcmp\(/tor_memeq\(/g' src/*/*.[ch]
perl -i -pe 's/0\s*!=\s*tor_memcmp\(/tor_memneq\(/g' src/*/*.[ch]
