__dllonexit

Registers a routine to be called at exit time.

Syntax

_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).

Requirements

Routine Required file
__dllonexit onexit.c
