RTMAC_WAIT_ON_xxx are generic cycle events, TDMA_WAIN_ON_xxx TDMA-specific. I tried to document this better in the header, see below and in SVN (I also took the chance to consolidate the numerical value of TDMA_WAIT_ON_SYNC, don't think anyone relies on binary compatibility here). Note that RTMAC_WAIT_ON_XMIT is yet unsupported by the TDMA RTmac device. This differentiation may appear confusing at first sight. The idea of RTmac is to support arbitrary media access disciplines, e.g. also a token-based protocol without a SYNC frame like TDMA. Then generic events are important to keep applications portable. Jan [from stack/include/rtmac.h] /* ** Common Cycle Event Types ** */ /* standard event, wake up once per cycle */ #define RTMAC_WAIT_ON_DEFAULT 0x00 /* wake up on media access of the station, may trigger multiple times per cycle */ #define RTMAC_WAIT_ON_XMIT 0x01 /* ** TDMA-specific Cycle Event Types ** */ /* tigger on on SYNC frame reception/transmission */ #define TDMA_WAIT_ON_SYNC RTMAC_WAIT_ON_DEFAULT #define TDMA_WAIT_ON_SOF TDMA_WAIT_ON_SYNC /*legacy support*/
