aoqi@0 | 51 | // system header files. On 32-bit architectures, there is no problem. |
aoqi@0 | 52 | // On 64-bit architectures, defining NULL as a 32-bit constant can cause |
aoqi@0 | 53 | // problems with varargs functions: C++ integral promotion rules say for |
aoqi@0 | 54 | // varargs, we pass the argument 0 as an int. So, if NULL was passed to a |
aoqi@0 | 55 | // varargs function it will remain 32-bits. Depending on the calling |
aoqi@0 | 56 | // convention of the machine, if the argument is passed on the stack then |
aoqi@0 | 57 | // only 32-bits of the "NULL" pointer may be initialized to zero. The |
aoqi@0 | 58 | // other 32-bits will be garbage. If the varargs function is expecting a |
aoqi@0 | 59 | // pointer when it extracts the argument, then we may have a problem. |
