    Thread-safety of API's

    robert.kliemann

      Hi,

         

      in my FX3-firmware I have two threads where one thread accesses one DMA-channel and another thread accesses another DMA-channel. For accessing the DMA-channels I use both the same API CyU3PDmaChannelGetBuffer(), CyU3PDmaChannelCommitBuffer() and CyU3PDmaChannelDiscardBuffer().

         

      Do I have to protect the accesses to the DMA-engine by a mutex so that only one thread accesses the same API or are the API's thread-safe in a way that in the API-implementation the accesses are already protected by mutexes?

         

       

         

      Regards,
