So standard exception "bad_alloc" will be used. 14 15 It's still allowed to use redefined version of operator "new" from "NewHandler.cpp" 16 with any compiler. 7-Zip's code can work with "bad_alloc" and "CNewException" exceptions. 17 But if you use some additional code (outside of 7-Zip's code), you must check 18 that redefined version of operator "new" (that throws CNewException) is not 19 problem for your code. 20 21 Also we declare delete(void *p) throw() that creates smaller code. 22 */ 23 24 25 class CNewException {}; 26 27 #ifdef WIN32 28 // We can compile my_new and my_delete with _fastcall 29 /* 30 void * my_new(size_t size); 31 void my_delete(void *p) throw(); 32 // void * my_Realloc(void *p, size_t newSize, size_t oldSize); 33 */ 34 #endif 35 36 #ifdef _WIN32 37 38 void * 39 #ifdef _MSC_VER 40 __cdecl 41 #endif 42 operator new(size_t size); 43 44 void 45 #ifdef _MSC_VER 46 __cdecl 47 #endif 48 operator delete(void *p) throw(); 49 50 #endif 51 52 /* 53 #ifdef _WIN32 54 void * 55 #ifdef _MSC_VER 56 __cdecl 57 #endif 58 operator new[](size_t size); 59 60 void 61 #ifdef _MSC_VER 62 __cdecl 63 #endif 64 operator delete[](void *p) throw(); 65 #endif 66 */ 67 68 #endif 69
