New Revision: 34489
Changeset: http://dev.haiku-os.org/changeset/34489/haiku

Modified:
   haiku/trunk/src/libs/compat/freebsd_network/Condvar.cpp
   haiku/trunk/src/libs/compat/freebsd_network/Condvar.h
   haiku/trunk/src/libs/compat/freebsd_network/Jamfile
   haiku/trunk/src/libs/compat/freebsd_network/compat/sys/condvar.h
Log:
Making use of the C++ structures in C only code feature introduced with
r34441. This allows to completely stick to FreeBSD's conditional cv_* function
semantics as 'struct cv' variables are freed automatically now.
This also gets rid of the dynamically de-/allocating of ConditionalVariables.
Thank you Ingo for helping me through this.
