So in any given whole process image, we may have   multiple definitions of each of these symbols.  In order to prevent   these definitions from conflicting with one another, and in order to   ensure that the proper lists are used for the initialization/finalization   of each individual shared library (respectively), we give these symbols   only internal (i.e. `static') linkage, and we also make it a point to   refer to only the __CTOR_END__ symbol in crtfini.o and the __DTOR_LIST__   symbol in crtinit.o, where they are defined.  */static func_ptr __CTOR_LIST__[1]  __attribute__ ((section (".ctors")))     = { (func_ptr) (-1) };static func_ptr __DTOR_LIST__[1]  __attribute__ ((section (".dtors")))     = { (func_ptr) (-1) };/* Run all the global destructors on exit from the program.  */ /* Some systems place the number of pointers in the first word of the   table.

There will be one of these   functions in each root executable and one in each shared library, but   although they all have the same code, each one is unique in that it   refers to one particular associated `__DTOR_LIST__' which belongs to the   same particular root executable or shared library file.  */static void __do_global_dtors ()asm ("__do_global_dtors") __attribute__ ((section (".text")));static void__do_global_dtors (){  func_ptr *p;  for (p = __DTOR_LIST__ + 1; *p; p++)    (*p) ();}/* .init section start.
