This command provides a mechanism to manipulate critical section objects. The legal options (which may be abbreviated) are:

• ns_critsec create

Initializes a new critical section object and returns a handle to it.

• ns_critsec destroy object

Destroys the critical section object and frees any resources it was using.

• ns_critsec enter object

Enters the critical section. The thread will block if another thread is already in the critical section.
