Branch condition evaluates to a garbage value when dereferencing a pointer to a pointer

Question

I'm trying to clean up some issues from xcode's analyzer. One I haven't found a solution to is the "Branch condition evaluates to a garbage value". It's occurring in the following way:

int methodToCloseMyDatabase(sqlite3 **myDatabase, const char *callingFunctionName)
{
    if (myDatabase)
    {
        if (*myDatabase)  // The warning is thrown here
        {
           // Do something
        }
    }
}

Answer 1

This error sounds to me as if CLang has analyzed your code and found that *myDatabase is not set to anything.

It could even be that the analyzer has found a possible code branch that does not set the value.

Answer 2

How did you set myDatabase ? You probably forgot to initialize it correctly, so it points to arbitrary place in memory.
