Is there any safe strcmp?
c, c++, strcmp
Solution
No, there's no (standard) way to tell whether a `char *` actually points to valid memory.
In your situation, it is better to use `std::string` rather than `char *`s for all your strings, along with the overloaded `==` operator. If you do this, the compiler would enforce type safety.
EDIT: As per the comments below if you find yourself in a situation where you sometimes pass `char *`s that may or may not be valid strings to functions that expect null-terminated strings then something is fundamentally wrong with your approach, so basically @janm's answer below.
Problem
I made a function like this: ``` bool IsSameString(char* p1, char* p2) { return 0 == strcmp(p1, p2); } ``` The problem is that sometimes, by mistake, arguments are passed which are not strings (meaning that `p1` or `p2` is not terminated with a null character). Then, `strcmp` continues comparing until it reaches non-accessible memory and crashes. Is there a safe version of `strcmp`? Or can I tell whether `p1` (and `p2`) is a string or not in a safe manner?
