RetroShare/libretroshare/src/tcponudp/tou.h
drbob 627b0f88a2 * Fixed up UDP Port "netReset()" (was stuck on 7812, now follows your tcp port).
* OSX Bug: doesn't like classes in C files. switched to void * pointer.
 * A little extra debugging in pqissl on disconnects.
 * switched on bitdht by default in libretroshare.pro
