|
|
|
82 // When __cplusplus is defined, NULL is defined as 0 (32-bit constant) in
|
|
|
83 // system header files. On 32-bit architectures, there is no problem.
|
|
|
84 // On 64-bit architectures, defining NULL as a 32-bit constant can cause
|
|
|
85 // problems with varargs functions: C++ integral promotion rules say for
|
|
|
86 // varargs, we pass the argument 0 as an int. So, if NULL was passed to a
|
|
|
87 // varargs function it will remain 32-bits. Depending on the calling
|
|
|
88 // convention of the machine, if the argument is passed on the stack then
|
|
|
89 // only 32-bits of the "NULL" pointer may be initialized to zero. The
|
|
|
90 // other 32-bits will be garbage. If the varargs function is expecting a
|
|
|
91 // pointer when it extracts the argument, then we have a problem.
|
|
|
92 //
|
|
|
93 // Solution: For 64-bit architectures, redefine NULL as 64-bit constant 0.
|
|
|
94 //
|
|
|
95 // Note: this fix doesn't work well on Linux because NULL will be overwritten

|
