/**
*
* @def TASK_ENTRY_MACRO( MyInitFn )
*
* set up a _start() task entry routine.
*
* MyInitFn should be declared in your task/namespace with one parameter,
* a reference to an errorlog.
*
* Example:
*
* static void init( errlHndl_t &io_rtaskRetErrl );
*
* Then if you wish to terminate with an error, say
*
* io_rtaskRetErrl = my_errl;
* return;
*
* This is not as flexible as the old TaskArgs setup but much simpler.
*
* Alternatively you can call task_end2() directly from the MyInitFn:
*
* task_end2( l_errl );
*
