Users may define up to 8 different timing baskets. A begin mark call establishes a high resolution starting time for the specified basket. An end mark call increments the specified basket counter, adds the elapsed time to the timing basket, and clears the starting time. Attempting to begin a mark that is not clear or end a mark that has not begun results in an error. The baskets are numbered from 0 to 7. Their results appear in the user snapshot structure in the smarkcnt and smarktim arrays.
User snapshots may include an optional function-timing array of ctWRKSTT structures as described in the Function Timing section below.
