PFLS_CALLBACK_FUNCTION callback function (winnt.h)
An application-defined function. If the FLS slot is in use, FlsCallback is called on fiber deletion, thread exit, and when an FLS index is freed. Specify this function when calling the FlsAlloc function. The PFLS_CALLBACK_FUNCTION type defines a pointer to this callback function. FlsCallback is a placeholder for the application-defined function name.

The value stored in the FLS slot for the calling fiber.

Remarks
Each FLS index has an associated FlsCallback function. The callback function can be used for any purpose, but it is intended to be used primarily to free memory.
