Macro Definition Documentation

◆ _Q_ASSERT

#define _Q_ASSERT (   a)

This file started as a copy of sys/queue.h from OpenBSD and then had various changes made over time. Now we include the system sys/queue.h and then add missing behavior. On Windows this means we basically add everything. This allows for Suricata builds that integrate with other libraries that make use of sys/queue.h to use the exact same definitions from queue.h instead the Suricata copy.
