50 // When __cplusplus is defined, NULL is defined as 0 (32-bit constant) in | |
51 // system header files. On 32-bit architectures, there is no problem. | |
52 // On 64-bit architectures, defining NULL as a 32-bit constant can cause | |
53 // problems with varargs functions: C++ integral promotion rules say for | |
54 // varargs, we pass the argument 0 as an int. So, if NULL was passed to a | |
55 // varargs function it will remain 32-bits. Depending on the calling | |
56 // convention of the machine, if the argument is passed on the stack then | |
57 // only 32-bits of the "NULL" pointer may be initialized to zero. The | |
58 // other 32-bits will be garbage. If the varargs function is expecting a | |
59 // pointer when it extracts the argument, then we may have a problem. | |
60 // | |
61 // Solution: For 64-bit architectures, redefine NULL as 64-bit constant 0. | |
62 #ifdef _LP64 | |
63 #undef NULL | |
64 // 64-bit Windows uses a P64 data model (not LP64, although we define _LP64) | |
