TlsFree function
Releases a thread local storage (TLS) index, making it available for reuse.
Syntax
BOOL WINAPI TlsFree( _In_ DWORD dwTlsIndex );
Parameters
- dwTlsIndex [in]
-
The TLS index that was allocated by the TlsAlloc function.
Return value
If the function succeeds, the return value is nonzero.
If the function fails, the return value is zero. To get extended error information, call GetLastError.
Remarks
If the threads of the process have allocated memory and stored a pointer to the memory in a TLS slot, they should free the memory before calling TlsFree. The TlsFree function does not free memory blocks whose addresses have been stored in the TLS slots associated with the TLS index. It is expected that DLLs call this function (if at all) only during DLL_PROCESS_DETACH.
For more information, see Thread Local Storage.
Examples
For an example, see Using Thread Local Storage or Using Thread Local Storage in a Dynamic-Link Library.
