… to previous dereference This rule finds comparisons of a pointer to null that occur after a reference of that pointer. It's likely either the check is not required and can be removed, or it should be moved to before the dereference so that a null pointer dereference does not occur. Recommendation The check should be moved to before the dereference, in a way that prevents a null pointer value from being dereferenced. If it's clear that the pointer cannot be null, consider removing the check instead.

Potential fix for code scanning alert no. 1: Redundant null check due to previous dereference

Security scanners are paranoid, and fixing everything to make them happy is not a good idea. BTW this function is not used, so I can't see if there's any mistake there. It appears to me like I created it during development, but went a different way later. "Width" parameter is not going to be null for this call, according to comment in header file. |
