Detailed Description

template<bool NESTED>
class UT_TaskLockT< NESTED >

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

Requirements:

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

Same as lock() except it also returns if it was the first time this task scope obtained the lock (ie. non-recursively).
