Function Documentation

void Ns_TlsAlloc	(	Ns_Tls *	keyPtr,
		Ns_TlsCleanup *	cleanup
	)

----------------------------------------------------------------------

Ns_TlsAlloc --

Allocate the next tls id.

Results: None.

Side effects: Id is set in given tlsPtr.

----------------------------------------------------------------------

void* Ns_TlsGet

(

Ns_Tls *

keyPtr

)

----------------------------------------------------------------------

Ns_TlsGet --

Get this thread's value in a tls slot.

Results: Pointer in slot.

Side effects: None.

----------------------------------------------------------------------

void Ns_TlsSet	(	Ns_Tls *	keyPtr,
		void *	value
	)

----------------------------------------------------------------------

Ns_TlsSet --

Set the value for a threads tls slot.

Results: None.

Side effects: None.

----------------------------------------------------------------------

void NsCleanupTls

(

void **

slots

)

----------------------------------------------------------------------

NsCleanupTls --

Cleanup thread local storage in LIFO order for an exiting thread. Note the careful use of the counters to keep iterating over the list, up to 5 times, until all TLS values are NULL. This emulates the Pthread TLS behavior which catches a destructor inadvertantly calling a library which resets a TLS value after it's been destroyed.

Results: None.

Side effects: Cleanup procs are invoked for non-null values.

Variable Documentation

int nsThreadMaxTls = NS_THREAD_MAXTLS

The following global variable specifies the maximum TLS id. Modifying this value has no effect.
