NAME

ns_mutex - Operate on mutexes

SYNOPSIS

ns_mutex option ?arg arg ...?

DESCRIPTION

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

• ns_mutex create

Initializes a new mutual exclusion (mutex) lock and returns a handle to it.

• ns_mutex destroy object

Destroys the mutex and frees any resources it was using.

NOTE: The mutex must be unlocked, or else the behavior is undefined and will likely crash the server. Before using this, you should probably look at Implementing a Mutex Pool instead.

• ns_mutex lock object

Attempt to acquire the mutex lock and block if it is already locked.

• ns_mutex unlock object

Release a previously acquired mutex lock.
