__dllonexit
Registers a routine to be called at exit time.
_onexit_t __dllonexit(
_onexit_t func,
_PVFV ** pbegin,
_PVFV ** pend
)
Parameters
func
Pointer to a function to be executed upon exit.pbegin
Pointer to a variable that points to the beginning of a list of functions to execute on detach.pend
Pointer to variable that points to the end of a list of functions to execute on detach.
Return Value
If successful, a pointer to the user’s function. Otherwise, a NULL pointer.
Remarks
The __dllonexit function is analogous to the _onexit function except that the global variables used by that function are not visible to this routine. Instead of global variables, this function uses the pbegin and pend parameters.
The _onexit and atexit functions in a DLL linked with MSVCRT.LIB must maintain their own atexit/_onexit list. This routine is the worker that gets called by such DLLs.
The _PVFV type is defined as typedef void (__cdecl *_PVFV)(void).
