Thread: Suspicious dereference of pointer

could you show the real code?

also how do you plan to check for NULL pointer if you have initialized the var to 1?

Is this being generated by a static analysis tool or the compiler? Which one?

Also, it's illegal to initialize a pointer to any literal constant other than 0. So I'm guessing this is not a compiler you are using.

Ah, but don't ignore it! Figure out why it's saying that. It might be a good reason and not using it will probably turn up bugs elsewhere.

First try to compile your code. Currently it doesn't. No point in running such tools if your code doesn't even compile.

As for the error itself, no code analysis tool worth its salt will flag "Suspicious dereference of pointer before NULL check" on the second line of the following snippet:

Code:

if (numMatches != NULL)
*numMatches = nRows //I got this error here only

Only exception is if NULL is being defined as something else. But being the case youcan't even compile your code, it's rather mute at this point to try and interpret the results of a code analysis tool.
