croutine. h @code{c} crSTART( CoRoutineHandle_t xHandle ); @endcode This macro MUST always be called at the start of a co-routine function. Example usage: @code{c} // Co-routine to be created. void vACoRoutine( CoRoutineHandle_t xHandle, UBaseType_t uxIndex ) { // Variables in co-routines must be declared static if they must maintain value across a blocking call. static int32_t ulAVariable; // Must start every co-routine with a call to crSTART(); crSTART( xHandle ); for( ;; ) { // Co-routine functionality goes here. } // Must end every co-routine with a call to crEND(); crEND(); } @endcode
