- * CommitThreadStack
- *
- * Commit the thread's entire stack. A thread's stack is usually only reserved memory, not committed. The OS will
- * commit more pages as the thread's stack grows. But, if the system is low on memory and disk space, its possible
- * that the OS will not have enough memory to grow the stack. That causes a stack overflow exception at very random
- * times, and the CLR can't handle that.
- *
- * Parameters:
- * The Thread object for this thread, if there is one. NULL otherwise.
- *
- * Returns:
- * TRUE if the function succeeded, FALSE otherwise.
