    Mimics "va_list" in OpenCL

    spectral

      Hi,

      I would like to be able to write some methods like this. I need a way to manage "dynamic parameters" like we do with va_list ...

      I know that internally you do this (with printf) but can we use this feature in OpenCL kernels ?

       

      Thanks
