This function releases a thread local storage (TLS) index, making it available for reuse.

Syntax

BOOL TlsFree(
  DWORD 
dwTlsIndex
);

Parameters

dwTlsIndex

[in] Specifies a TLS index that was allocated by the TlsAllocfunction.

Return Value

Nonzero indicates success. Zero indicates failure. To get extended error information, call GetLastError.

Remarks

If the threads of the process have allocated dynamic storage and used the TLS index to store pointers to this storage, they should free the storage before calling TlsFree.

The TlsFreefunction does not free dynamic storage that has been associated with the TLS index.

It is expected that DLLs only call this function during their process detach routine.

For a brief discussion of typical uses of the TLS functions, see the Remarks section of the TlsAllocfunction.

Requirements

Header winbase.h
Library coredll.lib
Windows Embedded CE Windows CE 1.0 and later
Windows Mobile Windows Mobile Version 5.0 and later
