LockCookie Structure

Defines the lock that implements single-writer/multiple-reader semantics. This is a value type.

Namespace:  System.Threading
Assembly:  mscorlib (in mscorlib.dll)

JScript supports the use of structures, but not the declaration of new ones.

The following example shows how to request a reader lock, upgrade the reader lock to a writer lock, and save the LockCookie. It then uses the LockCookie to downgrade to a reader lock again.

This code is part of a larger example provided for the ReaderWriterLock class.

No code example is currently available or this language may not be supported.

This type is thread safe.
