Any fiber in the process can subsequently use this index to store and retrieve values that are local to the fiber. Syntax C++ DWORD WINAPI FlsAlloc( __in PFLS_CALLBACK_FUNCTION lpCallback ); Parameters lpCallback [in] A pointer to the application-defined callback function of type PFLS_CALLBACK_FUNCTION. This parameter is optional. For more information, see FlsCallback . Return Value If the function succeeds, the return value is an FLS index initialized to zero. If the function fails, the return value is FLS_OUT_OF_INDEXES. To get extended error information, call GetLastError . Remarks The fibers of the process can use the FLS index in subsequent calls to the FlsFree , FlsSetValue , or FlsGetValue functions. FLS indexes are typically allocated during process or dynamic-link library (DLL) initialization. After an FLS index has been allocated, each fiber of the process can use it to access its own FLS storage slot. To store a value in its FLS slot, a fiber specifies the index in a call to FlsSetValue. The fiber specifies the same index in a subsequent call to FlsGetValue to retrieve the stored value. FLS indexes are not valid across process boundaries. A DLL cannot assume that an index assigned in one process is valid in another process.
