Saying Goodbye to C String Vulnerabilities: A Safer String Handling Approach
2024-12-21
Tired of C string vulnerabilities and insecurity? This article introduces a clever alternative: a custom string struct `struct str`, which contains a data pointer and length, avoiding the risks associated with null termination.

While using the macro `STR` is slightly verbose, the increase in safety and readability far outweighs this. Compiler optimizations also make the performance loss negligible, offering a new approach for developers prioritizing code security.
