Changeset 55980 in vbox for trunk/src/VBox/Runtime/common/log/log.cpp

Timestamp:

Message:

iprt/log.h,++: Added extended logger instance getters that also checks whether the given logger and group-flags are enabled, making the LogRel* checks more efficient in avoid uncessary RTLogLoggerEx parameter building and calls. Ditto for debug logging. The LOG_INSTANCE and LOG_REL_INSTANCE tricks are gone for now.
