Typedef Documentation

typedef UT_TaskLockT<true> UT_TaskLock

A recursive mutex class for synchronizing amongst tasks defined by UT_TaskScope.

The assumptions that UT_TaskScope uses for tasks are:

  • Tasks are hierarchical in a forest of trees
  • When child tasks are running, the parent task is not
  • Child tasks always finish before their parent task


  • You must unlock before your own task ends
  • You must unlock your lock before waiting for a child task to end
