Hi All,

Is there an option to initialize variables to known values in a C/C++ program?
My use case is 'debug' builds and finding use of uninitialized values
that get lucky by being 0 most of the time. For example:
void DoSomeithWithFoo(FOO** ppf) {
if(ppf && *ppf == NULL) {
*ppf = new FOO;
...
}
}
FOO* p;
DoSomeithWithFoo(&p);
So I would like something that initializes to known, but non-NULL,
such as 0xCDCDCDCD or 0xFDFDFDFD (similar to Visual Studio behavior).

Probably not, put =0, if I say "int x;" I am just saying there is an
int, it's name is x, deal with it. I may assign to it later, sticking =0
at the end implicitly wouldn't be good for anything really.
However! calloc initializes the memory to zero change malloc(size to
calloc(1,size and you're done.
Does that help?
